Mukul,
  Yes, that fixed it.  Thank you for your prompt reply.

Hi Jim,
    Thanks for sending across the schema and XML instance documents. I looked at the schema document you've shared.

The following fix seems to work for your problem <assert>,

<xsd:assert test="if (matches(string(@target), '.*')) then true() else false()"  xpathDefaultNamespace="##targetNamespace"/>

i.e, we use a string() function around attribute node @target. The 'target' attribute within your schema has type annotation of xsd:IDREFS, therefore we seem to need this workaround.
