Excellent! That's exactly what I was trying to achieve. Thanks.

It also seems that this may have answered my other question: about
saving the list of letters so I can iterate over them later (to make
links to the TOC entries.  It looks like I can just take the main
for-each loop and save that code to a variable.  I'll play with it.

I guess I need to play with the <xsl:key/>'s some more.  The code does
not seem obvious to me at all....
