Re: [ebxml-cppa] Data type for uuid attribute inProcessSpecificationelement in ebBPSS1.02.xsd

[Duane Nickull <duane@xmlglobal.com>]

Arvola:

I believe that is becuase the "xsd:id" datatype is to be used the same
as ID's in XML v 1.0.  It is not meant to be used for UUID's in the way
the ebXML requirements dictate (ie - globally unique).  I believe that
its' primary intended use was to be lexiaclly scoped to IDREF type
resolutions.

I may be wrong, however.  Maybe one of the XSD gurus can elaborate more?
