So, just to make sure I understand this right, for each descendent node,
you use this string-join function to build the full path via the
ancestors:

 -- string-join(ancestor-or-self::*/name(), '/')

Since you're doing this in the select clause of the for-each-group, the
things to be grouped are already the desired paths, so you just group-by
".".  And for the same reason, you can use "." in the concat clause to
format the output.

I would also get the same result by separating things like this, right?

<xsl:for-each-group select="//*"
group-by="string-join(ancestor-or-self::*/name(), '/')">
[blah....]
</xsl:for-each-group>

Guys, this is terrific.  Thanks very much for the prompt replies.
