Language reference: All-inclusive edition
The language reference portion of the DITA specification contains a topic for each DITA element. The topic defines the element, its inheritance hierarchy, and provides examples of usage. This portion of the DITA specification also includes information about DITA attributes.
Technical content elements
Elements in the technical content section include the original Concept, Task, and Reference specializations, as well as specializations added in later releases. It also includes domains designed primarily for technical content.
Reference elements
Reference topics describe factual material about a subject, such as the commands in a programming language. This format is also suitable for bibliographies, catalogues, the list of ingredients for recipes, and similar collections of structured descriptive prose. For more details on when to use reference and other information types, please refer to the DITA architectural specification.
<properties>
The <properties> element gives a list of properties for the subject of the current topic, for example whether a class is public or protected. Each property can include the type, value, and a description. The typical rendering is usually in a table-like format. To represent multiple values for a single type, create additional property elements and use only the <propvalue> element (and <propdesc> when needed) for each successive value.

Introduction to DITA 1.3
The Darwin Information Typing Architecture (DITA) specification defines a set of document types for authoring and organizing topic-oriented information, as well as a set of mechanisms for combining, extending, and constraining document types.
Architectural specification: All-inclusive edition
The architectural specification portion of the DITA specification outlines the framework of DITA. It contains an overview of DITA markup; addressing; processing; configuration, specialization, generalization, and constraints; as well as information about coding DITA grammar files.
Language reference: All-inclusive edition

- Element quick reference
  This section contains a listing of DITA elements.
- Topic elements
  The base topic elements include elements that make up the core building blocks of the DITA topic, such as topic, body, and related-links, as well as elements like <p> and <ph> that are used in many topic specializations. Some of these elements are also available inside the <topicmeta> map element.
- Map elements
  Map elements include the core components of DITA maps, such as <topicref> and <reltable>, as well as general purpose map specializations in the map group domain.
- Metadata elements
  Metadata elements include information that is located within the <topicmeta> element (in maps) or <prolog> element (in topics), as well as indexing elements that can be placed in additional locations within topic content.
- Domain elements
  General purpose domains are not specific to any type of information, such as the hazard statement domain that provides elements for describing hazardous situations.
- Classification elements
  Classification elements support managing metadata. Those in the subject scheme map are used to define controlled values and to bind the controlled values to DITA attributes as enumerations. Those declared in the classification domain are used in other maps to classify content according to the scheme.
- Specialization elements
  Several DITA elements exist either for architectural reasons or for support of specialized markup yet to be designed. Although there is little need to use these elements unless you are directed to, some of them, such as <state>, can be used if your content makes use of these semantic distinctions. For example, a discussion of signals on a gate of an integrated logic circuit might use the <state> element to represent either on or off conditions of that gate.
- Legacy conversion elements
  Conversion elements exist primarily to aid in the conversion of content to DITA.
- DITAVAL elements
  A conditional processing profile (DITAVAL file) is used to identify which values are to be used for conditional processing during a particular output, build, or some other purpose. The profile should have an extension of .ditaval.
- Technical content elements
  Elements in the technical content section include the original Concept, Task, and Reference specializations, as well as specializations added in later releases. It also includes domains designed primarily for technical content.
  - Concept elements
    DITA concept topics answer "What is..." questions. Use the concept topic to introduce the background or overview information for tasks or reference topics. The concept topic restricts content following a section or example to other sections or examples. For more details on when to use concept and other information types, please refer to the DITA architectural specification.
  - Task elements
    Task topics answer "How do I?" questions, and have a well-defined structure that describes how to complete a procedure to accomplish a specific goal. Use the task topic to describe the steps of a particular task, or to provide an overview of a higher-level task. The task topic includes sections for describing the context, prerequisites, actual steps, expected results, example, and expected next steps for a task. For more details on when to use task and other information types, please refer to the DITA architectural specification.
  - Reference elements
    Reference topics describe factual material about a subject, such as the commands in a programming language. This format is also suitable for bibliographies, catalogues, the list of ingredients for recipes, and similar collections of structured descriptive prose. For more details on when to use reference and other information types, please refer to the DITA architectural specification.
    - <reference>
      The <reference> element defines a top-level container for a reference topic. Reference topics document programming constructs or facts about a product. Examples of reference topics include (but are not limited to) product specifications, environmental specifications, equipment lists, parts lists, required tools, language elements, class descriptions, commands, functions, and API information. All of these topics provide quick access to facts, but they do not contain a deeper explanation of related concepts or tasks.
    - <refbody>
      The <refbody> element is a container for the main content of the reference topic. Reference topics limit the body structure to tables (both simple and standard), property lists, syntax sections, and generic sections and examples, in any sequence or number.
    - <refbodydiv>
      The <refbodydiv> element is similar to the <bodydiv> element in that it provides an informal container for content that might be grouped within a reference. Reference topics place many restrictions on their content compared to generic topics; the <refbodydiv> element maintains these restrictions by only allowing elements that are already available within the body of a reference. There are no additional semantics attached to the <refbodydiv> element; it is purely a grouping element provided to help organize content.
    - <refsyn>
      The <refsyn> element is a special section inside a reference topic. The section often contains syntax or signature content (for example, the calling syntax for a command-line utility or an API signature). The <refsyn> contains a brief, possibly diagrammatic description of the subject's interface or high-level structure.
    - <properties>
      The <properties> element gives a list of properties for the subject of the current topic, for example whether a class is public or protected. Each property can include the type, value, and a description. The typical rendering is usually in a table-like format. To represent multiple values for a single type, create additional property elements and use only the <propvalue> element (and <propdesc> when needed) for each successive value.
    - <prophead>
      The <prophead> element supports headings for the <properties> element.
    - <proptypehd>
      The <proptypehd> element supports headings for the type column of a properties table.
    - <propvaluehd>
      The <propvaluehd> element supports headings for the value column of a properties table.
    - <propdeschd>
      The <propdeschd> element supports headings for the description column of a properties table.
    - <property>
      The <property> element represents a single property of the current topic's subject. For example, if the current reference topic describes a programming class, the property might show that the class is protected rather than public. The <property> element generally appears together with a series of other properties; it contains three optional elements to provide a type, value, or description of the property.
    - <proptype>
      The <proptype> element describes the type of the property.
    - <propvalue>
      The <propvalue> element indicates one or more values for the current property type. Values can be placed in separate <property> elements if they need separate descriptions. The <proptype> element need not be repeated.
    - <propdesc>
      The <propdesc> element is used to provide a short description of the property type and its listed values.
  - Troubleshooting elements
    Troubleshooting topics document corrective action such as troubleshooting or alarm clearing.
  - Glossary elements
    Glossary elements include those elements designed to specify terms and their definitions, as well as elements that are designed to group, reference, or otherwise make use of information in the glossentry topic.
  - Bookmap elements
    Elements in the bookmap section are used to organize DITA content into book form. They include elements for dividing up content, such as chapter and appendix, as well as metadata specific to publishing.
  - Technical-content domains elements
    Domains in this section include those generally associated with technical content, such as the programming and software domains.
- Learning and training elements
  Elements in the learning and training section include specialized topics, maps, content, and metadata elements specially designed to support instructional content.
- Attributes
  This section collects commonly used attributes, with common definitions. If an element uses a different definition, or narrows the scope of, an otherwise common attribute, it will be called out in the topic that defines the element.
Conformance
Conformance to the DITA specification allows documents and document types that are used with different processors or different versions of a processor to produce the same or similar results with little or no reimplementation or modification.
Acknowledgments

Content models for learning and training package
For each element in the learning and training package, this section presents the content model and a list of parent elements that can contain that element.

`<properties>`

The <properties> element gives a list of properties for the subject of the current topic, for example whether a class is public or protected. Each property can include the type, value, and a description. The typical rendering is usually in a table-like format. To represent multiple values for a single type, create additional property elements and use only the <propvalue> element (and <propdesc> when needed) for each successive value.
