distinct-values in Where Clauses

you probably don't want another where clause (The where clause that you
have also needs to change as calling distinct-values on a sequence of
length 1 will never do anything very useful.

If the problem you are having is that
$head in $find/head,
is returning multiple head elements, then change it so that it only
selects 1, for example
$head in $find/head[1] would always use the first
or
$head in $find/head[not(@type) or  @type='main']
would only select main (or unclassified) heads.

Only you can know what your requirements are.
