Re: default namespaces in Schematron

It does not matter how the namespace is specified in the XML instance. Just declare the namespace with an ns element in Schematron and use that prefix to refer to elements from that namespace.

Hello.

Does anybody know how to specify default namespaces in Schematron?

Given the following sort of XML:

<root>
<foo/>
</root>

And the following sort of SCH:

<schema xmlns="http://purl.oclc.org/dsdl/schematron">
<pattern>
<rule context="foo">
<assert test="bar">foo must have bar</assert>
</rule>
</pattern>
</schema>

A Schematron validator correctly asserts that <foo> is missing a child
<bar>.

However, as soon as I assign a namespace to the XML:

<root xmlns="http://my.server.com">

the Schematron rule fails to match.  Presumably, this is because the
element <foo> is now in the "http://my.server.com" namespace.

Schematron allows a <ns> element to solve just this problem.  But it
requires a uri and a prefix.  The above, being a default namespace, has
no prefix.

Any ideas?

Thanks
