Re: Errors in ebXML Message Service Spec 1.0?

[Arvola Chan <arvola@tibco.com>]

Robert:

I am on the subcommittee working on the 1.1 revision. Attached
please find the files that have been updated to conform to the
W3C Recommended version of XML Schema. I will be interested
in hearing if you find any problem in using the revised schema.

Please note that the file messageHeaderv1_1.xsd assumes the
other files are located in c:\ebxml.

Cheers,
-Arvola
