What is the sequence of elements in a schema that validate a particular tag?
I have been working on an issue involving xml schema for a while now that
seems like it should have a simple solution but at this point I have not
been able to find one.
I have xml defined as follows
<start>
<myelement>test</myelement>
</start>
I validate it against the following schema.
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:group name='mygroup1'>
<xsd:sequence>
<xsd:element name='myelement' type='xsd:string'/>
</xsd:sequence>
</xsd:group>
<xsd:complexType name='mycomplextype'>
<xsd:choice>
<xsd:group ref='mygroup1'/>
<xsd:element name='myelement' type='xsd:string'/>
</xsd:choice>
</xsd:complexType>
<xsd:element name='start' type='mycomplextype'/>
</xsd:schema>
The issue I am having is that I need to know what elements in the xml schema
were used to validate the "myelement" tag. Within the mycomplextype the
group reference may of been used or the element definition may of been used.
Is there anyway which I can figure out what the path was that was done for
validation?
For example was it element/complexType/choice/group/sequence/element or was
it element/complexType/choice/element
I looked into using PSVI to determine what it was, but it does not appear to
contain the functionality I need.

The schema is invalid since it violates the Unique Particle Attribution
rule (http://www.w3.org/TR/xmlschema-1/#non-ambig).
