Hi Kasimier,

It seems that Libmxl2 don't have full support for XML Schema, but I =
change
the XSD a little bit to workaround with this Libxml2 limitation.

The second version is here:

 Hi,
=20
 (this is a handmade reply to the mail from Lars Martin,
 since I just subscribed)
=20
 Occurences must not be specified on the model group
 child of model group definitions.
=20
 With Libxml2 I get:
=20
 xmllint --noout --schema XUpdate.xsd xudummy.xml
=20
 XUpdate.xsd:44: element choice: Schemas parser error : Element
  "{http://www.w3.org/2001/XMLSchema}choice": The attribute
  "minOccurs" is not allowed.
 XUpdate.xsd:44: element choice: Schemas parser error : Element
  "{http://www.w3.org/2001/XMLSchema}choice": The attribute
  "maxOccurs" is not allowed.
 WXS schema XUpdate.xsd failed to compile
=20
 The occurences need to be moved to each of the model group
 references.
=20
 Regards,
=20
