No need for an intermediate fragment.  This is a simple grouping problem, just 
with the additional complexity of the different meanings of the different 
elements.

I'm a little confused on your logic though.

Let me try and guess the rules:

* For <foobar> elements, output @name if it is the first of 
(foobar/@name|bar/@name1|bar/@name2) with the given value.

* For <bar> elements, output @name1 and @name2 if they are the first of 
(foobar/@name|bar/@name1|bar/@name2) with the given value and if the value is 
not a value of a foo/@name.

Or, another guess:

* You want to treat foobar/@name, bar/@name1, and bar/@name2 as all the same, 
and foo/@name is always not output?

I'd be happy to help suggest a solution, but I don't want to waste my time if 
my guesses are not correct.  Can you clarify a little bit?
