   As others have already mentioned, it is a good idea to use several tools.
XMLSpy doesn't catch quite everything, and sometimes tools will disagree.
The IBM Schema Checker is of great help.

   However, for your specific problem, the fix is relatively easy (we had a
similar situation). I'm assuming you have a group defined, and within that
group a choice (with a min and/or max occurance value set). Instead of
placing the min/max on the choice, place the min/max on the group instead.
Doing this also fixed a perceived bug in XMLSpy's graphical schema display
(it was doing something strange with the <include>'ed files when viewed from
the top-level schema). So even though XMLSpy is not catching the error, it
is certainly affected by it. Hope this helps.

Subject: Schema migration blues, Help needed


I am attempting to migrate a schema that used to work with Xerces-1.3.0 to
the new Xerces-1.4.1

I realize that the schema specifications have changed so I used XMLSpy to
convert my schema's and XML files. The Files validate OK in XMLSpy but fail
validation using the Xerces 1.4.1 parser when the following properties are
turned on: "http://xml.org/sax/features/validation" and
"http://apache.org/xml/features/validation/schema".

The problem is that during validation the parser seems to discover errors in
the conformance to the specifications (e.g. The child 'xsd:choice' of the
named group definition 'attribute_decl' must not specify either the
minOccurs or maxOccurs attribute) that XMLSpy 4.0 does not complain about.

Has anyone been down this path before? If so would you kindly share your
experiences with me, perhaps point me to some information that could help in
my migration efforts?

Thanks in advance,

Michael Petres
