Reasons

Main: We knew such tight schedule was unrealistic (6 months for PR?), but better slip once than twice...

Second: big amount of time spent in review and coordination: XML-Schema and XSL:

A (December 2000): OK
B (April 2000): OK
...	7 April 2000: XML-Schema goes to Last Call
...		June 2000: XSL restarts for XSLT2.0 and XPATH2.0
...	24 October 2000: XML-Schema goes to CR
C (November 2000): NOPE

Non-Reasons:

• Big size of the wg
• Lack of technical expertize

Benefits:

• Fostered extremely benefical and productive cooperation among Working Groups.
