Well, I tried  that, several other permutations, and couldn't get
anywhere.  I did figure out a way to solve the problem though.  I use
my for-each to build up a string which is then passed to a template I
call uniq.  The parameter passed in looks something like:
	 |z|a|b|c|a|b|c|b|b|y|z|
That is, a "string list" with '|' as a separator.  My uniq template
uses the string functions substring-before, substring-after, &
contains to recursively make that into a unique list.

That's a lot of work for such a simple thing (simple in procedural
languages).  But at least I've got something working now.
