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.
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.
Universal attribute group
The universal attribute group defines a set of common attributes available on most DITA elements. The universal attribute group includes all attributes from the metadata, ID, localization, and debug attribute groups, plus the @class attribute.
Localization attribute group
The localization attribute group defines a set of common attributes related to translation and localization. These attributes are available on most DITA elements.

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.

- 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.
- 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.
  - Universal attribute group
    The universal attribute group defines a set of common attributes available on most DITA elements. The universal attribute group includes all attributes from the metadata, ID, localization, and debug attribute groups, plus the @class attribute.
    - ID attribute group
      The ID attribute group includes attributes that enable the naming and referencing of elements in topics and maps.
    - Metadata attribute group
      The metadata attribute group includes common metadata attributes, several of which support conditional processing (filtering and flagging) or the creation of new attribute domain specializations.
    - Localization attribute group
      The localization attribute group defines a set of common attributes related to translation and localization. These attributes are available on most DITA elements.
    - Debug attribute group
      The debug attributes group includes a set of debugging attributes that are normally hidden from authoring view. These attributes are defined for every DITA element.
  - Architectural attribute group
    The architectural attributes group includes a set of attributes defined for document level elements such as <topic> and <map>. These attributes are intended to provide information about the DITA namespace, what level of DITA is in use, and what vocabulary modules are in use.
  - Attributes common to many map elements
    This attribute group collects several attributes that are used on a variety of map elements. For a few elements, the group is modified slightly to remove an attribute such as @toc or @format; in those cases the element definition will clarify that the element does not use this full set. That is generally done in order to specify a default for one attribute, such as defaulting @format to "ditamap" on the <mapref> element.
  - Complex-table attribute group
    The Complex-table attribute group includes several attributes that are defined on complex table elements. Most of these attributes are part of the OASIS Exchange model; table elements generally use only a subset of the attributes defined in this group. These attributes are not available for the <simpletable> elements.
  - Data element attributes group
    The data element attributes group includes attributes that are defined for the <data> element, and are reused on most or all specializations of the <data> element.
  - Date attributes group
    The date attributes group includes attributes that take date values, and are defined on metadata elements that work with date information.
  - Display attribute group
    The display attribute group includes attributes whose values can be used for affecting the display of many elements.
  - Link relationship attribute group
    The link relationship attribute group includes attributes whose values can be used for representing navigational relationships. These attributes occur only on elements that represent relationships among DITA elements or between DITA elements and non-DITA resources.
  - Other common attributes
    These common attributes are used across a wide variety of elements, with the common definition included below. These attributes are not defined as a group, and many elements only specify one or two from this list.
  - Simpletable attribute group
    The simpletable attribute group includes several attributes that are defined on the <simpletable> element and <simpletable> specializations. These attributes are not defined for the OASIS exchange table (<table>).
  - Specialization attributes group
    These attributes are designed to be used by specializers, and are not intended for direct use by authors.
  - Topicref element attributes group
    The topicref element attributes group includes attributes that are defined for the <topicref> element, and are reused on most or all specializations of the <topicref> element.
  - Complex attribute definitions
    Several DITA attributes require more explanation than can fit in a single table cell. Those attributes are collected here.
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
(Non-normative) Many members of the OASIS DITA Technical Committee participated in the creation of this specification and are gratefully acknowledged.
Non-normative information
This section contains non-normative information, including topics about new features in DITA 1.3 and migrating from DITA 1.2 to DITA 1.3.
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.

Localization attribute group

The localization attribute group defines a set of common attributes related to translation and localization. These attributes are available on most DITA elements.

@translate: Indicates whether the content of the element should be translated or not. Allowable values are yes, no, and -dita-use-conref-target. See Element-by-element recommendations for translators: All-inclusive edition for suggested processing defaults for each element.
@xml:lang: Specifies the language of the element content. The @xml:lang attribute and its values are described in the XML Recommendation at http://www.w3.org/TR/REC-xml/#sec-lang-tag. Allowable values are language tokens or the null string.
@dir: Specifies the directionality of text: left-to-right (ltr, the processing default) or right-to-left (rtl). The value lro indicates an override of normal bidi text presentation, forcing the element into left-to-right mode; rlo overrides normal rules to force right-to-left presentation. Allowable values are ltr, rtl, lro, rlo, and -dita-use-conref-target. See The dir attribute for more information.

The @translate, @xml:lang, and @dir attributes identify language-specific words or phrases for specific processing (or non-processing, in the case of translate="no").

<p>The cordial response to the question is 
<q translate="no" xml:lang="de-de" dir="ltr">nein.</q></p>
