I should think a key using the initial letter of each name would be a big help:
<xsl:key name="person-by-initial" match="person" use="substring(@name,1,1)"/>
Then "key('person-by-initial', 'A')" would get you back the elements for Anthony, Amy and the other Amy, and "key('person-by-initial', 'A')[1]" would get you just Anthony.
//person[count(.|key('person-by-initial', @name)[1]) = 1] gets you all person elements that are first with their initial.
In other words, the usual grouping stuff.

I would expect to get A,J from the above XML
Here's most of it for you. I'm having trouble with the initial variable selection though. I'm hoping somebody can take it from here, as I'm stumped now too....
