That was my bad.  It was from an example I posted,  except 'child::'
was 'preceding-sibling::' in my function.

It's in that form because the previous version had a string() around
$r to show how you could write your own function that emulated the
results of the distinct-values() function.

It did not occur to me at the time to simplify the expression, but it
makes sense when you pointed it out.

Thanks.
