 RE: Question about grouping attributes using keys
Got it:
 - * selects any element
 - @* selects any attribute

So changing my for-each to grab both:
<xsl:for-each
select="ROOT/ITEM[generate-id()=generate-id(key($theKey,(*|@*)[local-nam
e()=$theName])[1])]">

And doing the same when printing the value:
<xsl:value-of select="(*|@*)[local-name()=$theName]" />

Seems to do the trick...

Weird...in the Xpath specs,  "A node test node() is true for any node of
any type whatsoever."
But in the XSLT specs, "node() matches any node other than an attribute
node and the root node"

Is there any way to select "any node of any type" in XSLT 1.0?  That
would make things much easier.

Thanks for your help, as always

>I'm trying to write a generic function to output a list of unique
values on a selected node, whether it be an Element or Attribute.  I've
got the Element portion working fine, but Attributes don't seem to want
to run through the for-each loop....  Here's a test which highlights
this:
