Hi,
I have been trying to import an XML Schema file (via Eclipse into a new
EMF Java project) and each time it came back with the same error:
Problems were detected while validating and converting the XML Schemas
Error: XSD: The element 'http://www.trip.org/schema/trip#name' may not
overlap with a wildcard allowing its namespace : URI
file:/C:/appdev/HAREGISTRY/problem_example.xsd Line 4 Column 3
Error: XSD: The element 'http://www.trip.org/schema/trip#linkDistance'
may not overlap with a wildcard allowing its namespace : URI
file:/C:/appdev/HAREGISTRY/problem_example.xsd Line 4 Column 3
Error: XSD: The element 'http://www.trip.org/schema/trip#linkDistance'
may not overlap with a wildcard allowing its namespace : URI
file:/C:/appdev/HAREGISTRY/problem_example.xsd Line 4 Column 3
I have included below a cut down version of the schema that highlights the
problem. It does import if (1) the xsd:any is removed or (2) the
minOccurs="0"
is removed for the xsd:element name="linkDistance"?
Can anyone suggest if this is an issue/bug with XSD or with the XML Schema
I
am dealing with?
Thanks for any help,
Alastair

Alastair,
Your schema violates the Unique Particle Attribute rule from appendix H
in the spec. This is a very hard constraint to check, so many
validators don't bother. When parsing an instance that starts with
<name> and is followed by <linkDistance> it will be ambiguous whether
<linkDistance> matches the <linkDistance> element in the grammar, or
whether it matches the <any> in the grammar, with the <linkDistance>
element being missing as allowed by the fact that it's optional in the
grammar.
