But not that distinct-values returns a sequence of atomic values,
*not* nodes.  If the operands are nodes, their typed value (i.e.
a string since we don't have schemas) is extracted.  And you can't
get the parent of a string.

Of course that assumes you're using the standard distinct-values
function.  If you're using the implementation I posted, that might
work accidentally.  If not, it could be the basis for something that
does what you need - but you should rename it if you're depending
on non-standard behavior.
