oxy:is-editable-element() Function

This function checks if the element returned by the given XPath expression is editable (content can be inserted in it), meaning both that the entire XML file is editable and that the current context where the element is placed is editable. For example, if the element is inside an xi:included section, it is not editable.

It only has one argument, an XPath expression, and the XPath expression must be written in such a way that it returns a single element.

oxy:is-editable-element(ancestor-or-self::table)

This example would return true if the cursor is placed inside a table and it is editable or false if it is not editable.
