Is there any way to match an attribute's value to the value in an
ancestor's attribute?

For example, given the XML fragment:

<test version="1">
  <item version="2">this is version 2</item>
  <item version="1">this is version 1</item>
</test>

I'd like to write an XSL pattern (a match pattern, methinks) which will
match the <item> with the same version number as <test>.  Something like
item[attribute(version)]=test[attribute(version)], conceptually.

Is tihs possible?  If not, any recommendations on some sort of workaround?

Thanks,

dwh
