The W3C XML Schema specifications (0 1 2) have reached Proposed Recommendation status.

In a message to XML-dev, Rick Jelliffe noted that:

"The new specifications have been thoroughly revised, restructured and reformatted for clarity. [...] there are now more examples, better overview and navigation material, fluff has been cut, the Primer provides a very nice introduction for the laity, there is a formalization in the works (MSL) which will help type-theorists, and there is even a couple of pictures now."

The namespace for XML Schema has changed to http://www.w3.org/2001/XMLSchema, and that location now hosts a RDDL description of W3C XML Schema. The XML Schema instance namespace has changed to http://www.w3.org/2001/XMLSchema-instance.

Lists of changes from the previous Structures draft and changes from the previous Datatypes draft are available.

The comment period for all three specifications ends 16 April 2001.
