One other thought on this. The reason it is important to know if I don't have a match is that there should always be a match and it is important to report this state.

Wouldn't this be satisfied with the following using priority?

  <xsl:template match="node()|@*" priority="-1">
    <xsl:message>Not handled: .....

... or even better using importance:

<xsl:import href="debug.xsl"/>

  <xsl:template match="node()|@*">
    <xsl:message>Not handled: .....

I have this in most of my stylesheets ... I put this lowest importance imported template into my import tree so as not to interfere with my other template rules and to tell me what isn't being handled by my code.

Such a template rule overrides the built-in template rules and is less important than all of my own template rules, so it catches what I don't catch in my other template rules.

I hope this helps.
