[oXygen-user] Setting up catalog files for W3C XML Schemas

Hi,

I have downloaded the schemas from http://schemas.opengis.net/ows/0.3.2/.
The schemas refer to xlink which I already have on my system in
e:/downloads/GML3.1/GML2004-10-29/xlink/xlinks.xsd.  Rather than change the
schemaLocation in the ows19115subset.xsd file I thought that I would use a
catalog file to tell Oxygen 5.0 to find a local copy.

The default catalog file in "Options => Preferences => XML Catalog" is
file:/C:/Program Files/Oxygen 5.0/frameworks/catalog.xml. I edited this file
by adding the following line:

  <nextCatalog catalog="e:/downloads/oxygencatalog.xml"/>

and added the following lines in the e:/downloads/oxygencatalog.xml" file:

<?xml version="1.0" encoding="UTF-8"?>
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog">
   <rewriteURI
    uriStartString="http://www.w3.org/1999/xlink/"
    rewritePrefix="GML3.1/GML2004-10-29/xlink/"/>
</catalog>

If I open all the ows schemas into a project and then try to validate the
project I get the following error:

http://www.w3.org/TR/xmlschema-1/#src-resolve	E src-resolve: Cannot resolve
the name 'xlink:simpleLink' to a(n) 'attribute group' component.
ows19115subset.xsd	file:/E:/downloads/ows2/ows19115subset.xsd
111:43

Yet the "simpleLink" attribute group is defined in xlinks.xsd as follows:

	<attributeGroup name="simpleLink">
		<attribute name="type" type="string" fixed="simple"
form="qualified"/>
		<attribute ref="xlink:href" use="optional"/>
		<attribute ref="xlink:role" use="optional"/>
		<attribute ref="xlink:arcrole" use="optional"/>
		<attribute ref="xlink:title" use="optional"/>
		<attribute ref="xlink:show" use="optional"/>
		<attribute ref="xlink:actuate" use="optional"/>
	</attributeGroup>

Am I not using the catalog file syntax properly or is there a mismatch
between the ows XSDs and xlink?

Thanks.
