Changes from DITA 1.0 to DITA 1.1
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
