W3C XML Schema did not change XPath expression semantics, so you
_must_ use prefixes to match qualified names.
I should have clarified that in my example I removed the namespace
declaration from the instance - - it was faster that way.
But adding it back in properly and XSV still finds the errors:
site.xsd:
<schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:foo">
<element name="Site" type="anyType">
<unique name="idName">
<selector xpath=".//*"/>
<field xpath="@name"/>
</unique>
</element>
</schema>
site.xml:
<Site xmlns="urn:foo">
<Home name="CorHome">
<Topic name="Your_Needs">
<View name="Choice_1"/>
<View name="CorHome"/>
<View name="Your_Needs2"/>
</Topic>
<Topic name="Your_Needs2">
<View name="Choice_3"/>
<View name="Choice_4"/>
<View name="Choice_3"/>
</Topic>
<Topic name="Your_Needs"/>
</Home>
</Site>
