This is true with one tiny caveat: if indexterm ever has mixed 
content, particularly more than one text node. I don't think you want 
any indexterms with more than a single text node to appear as many 
times as they have text nodes, each time with that fragment of text. 
(This can sometimes happen if comments or processing instructions, 
not only inline elements, happen to intervene.)

<indexterm>Global <!-- was "World" -->Health</indexterm>

There are two text nodes there, with the values "Global " and "Health".

That's another reason why group-by="(@term.entry,.)[1]" is probably better.

Or, in Gerrit's more transparent style, "if (@term.entry) then 
@term.entry else ."

Cheers,
Wendell
