I looked at how the indexing templates work, and they
are using string functions applied to <indexterm> subelements
like <primary>.  When you process an element in the context
of a string, you get just the text data from the
element.  Since <xref/> is empty, it has no text data, so
the index term is processed as if it were empty.
There is no "apply-templates" step that would resolve the
xref to text.

I don't know how hard it would be to change that behavior.
