The DITA 1.1 specification was designed to be backwards-compatible with applications
that conform to the DITA 1.0 specification.
The following major changes to the architecture provided added functionality for DITA 1.1:
- A
<bookmap>
specialization for encoding book-specific information in a DITA map
- A
<glossentry>
specialization for glossary entries
- Indexing specializations for see, see-also, page ranges, and sort order
- Improvements to graphic scaling capability
- Improved short description flexibility through a new
<abstract>
element
- Specialization support for new global attributes, such as conditional processing
attributes
- Support for integration of existing content structures through the
<foreign>
element
- Support for new kinds of information and structures through the
<data>
and
<unknown>
elements
- Formalization of conditional processing profiles
