[xsl] XML Schema 1.0 files

[davep <davep@xxxxxxxxxxxxx>]

Given an XML schema, I want to find files containing definitions & 
references  of a particular element

Root is

<xsd:schema xmlns="http://www.x";
	targetNamespace="http://www.x";
  ...

Later I see

<xsd:element ref="X"/>

and

<xsd:element name="X">
but also
<xsd:element ref="dc:X"/>


I'm looking for some xslt 2.0 that will combine
them to search for element X definitions and references
and report their namespace.
I'm working on a directory, so I'll be using collection() but
for one file all I want to know is
if element X (ref or def) is in the  file, and if so, what the 
appropriate namespace is.
So the stylesheet parameters are the localname and the
returned value either nothing (not found) or the namespace in which the
element is, indicating it was found?
AFAICT in the above example, the namespace is /xsd:schema/@targetNamespace

Has anyone done this before please?

TiA
