The description element

On this page:

The description element is the root container element for a description. It consists of an optional container element for metadata information (the head ) and a required container for the different description types and alternate image renditions (the body ).

The language of the description can be specified by attaching an xml:lang attribute to the description element. If the description will be made available in a standalone context (i.e., in which its language cannot be inherited from a host content document), the language should always be specified.

The DIAGRAM Description profile provides the ability to compile one or more description elements into a single document for distribution (e.g., to accompany an EPUB).

When storing a description in a standalone context, the Description feature namespace http://www.daisy.org/ns/z3998/authoring/features/description/ should be declared on the description element using the xmlns namespace association mechanism defined in XMLNAMES . Although not required, the prefix d is recommended.
