XML Adapter V4.2 - W3C XML Schema Support

Does anybody know when the updated release of the Enterprise XML Adapter V4.2 will be released to support W3C XML Schemas with syntaxes from the March 2001 version or later?

I am currently trying to use a schema in the XML parse operation and get the following error message:

“The adapter process is unable to supply a valid set of values for the following reason: (301) Unable to parse … for DTD or Schema.
com.wm.util.LocalizedException: … - this schema definition is written using syntaxes from the W3C XML Schema Proposed Recommendation drafts, dated March 2001 or later. B2B does not support this version and will support it in the near future.”

Has anybody got a work around for this issue?
