Since the W3C specification for XQuery is not yet finalized, neither is the implementation of Tamino XQuery 4. It is currently mainly based on the draft specifications from August 16, 2002 and from November 12, 2003, but lacks some of the features mentioned therein. This document describes the most important of them. The mention of a feature here does not imply that Software AG hereby makes a commitment to implement this functionality. If a feature is not mentioned, this does not imply that it has been implemented, as the list is not complete.
