No I'm not. I want
<someting sex='M M"/>
then I could count them.
and if it was
<foo bar="...."/> where the sequence of @bar's take on several distinct
overlapping values I may want to union or interesect them
and if @bar didn't taken on overlapping values I may want to return them as
a list.
I don't know how much clearer I can make this.
