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"/>

  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.
