RE: Redefinition of group, who's correct

Surprised there are people who still use XMLSpy. Are they not a dying breed?

XMLSpy has a totally different interpretation of the schema 1.0 spec concerning xs:redefine.
See e.g http://lists.w3.org/Archives/Public/xmlschema-dev/2004Dec/0048.html


I have a had contact with Altova (the developers of XMLSpy) several times and their answer is something like "we are right and the rest of the world is wrong ..."
The CDISC standards make a lot usage of xs:redefine, reason the issue came up in our working group.
So we wrote a "white paper" for the FDA stating that XMLSpy is not a suitable tool for validating CDISC-XML documents.

With best regards,
