RE: [xsl] xsl template priority / xsl template precedence

["Michael Kay" <mike@xxxxxxxxxxxx>]

You've got one template that matches aggregate elements, and another that
matches errorresponse elements. Priorities only come into play when a node
matches more than one template rule, and that's not the case here - there's
no overlap. If you apply-templates on an aggregate, the first rule fires; if
you apply-templates on an errorresponse (with the right ancestry) the second
rule fires. Priority and precedence don't affect it.
