Re: regular expression matching in <assert>

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.
