The W3C has released a Last Call draft of the XML Information Set. Comments are due by 31 January 2000.

A few of the changes include:

• the XML version number is now explicitly not a part of the information set
• the document has been reorganized - XML 1.0 Reporting Requirements, for instance, have been moved to an appendix
• namespace processing has been much more tightly integrated with the infoset
• an RDF schema is provided
• required materials are now called 'core' while optional materials are now called 'peripheral'
