That's not so bad. Use the union operator for node-sets:

//user[@username='evitiello']//right | //group[@name=$usergroups]//right

or even

(//user[@username='evitiello'] | //group[@name=$usergroups])//right

(keeping in mind there are ways to avoid the costly // traversals given 
information about document structure, context nodes and the uniqueness of 
values)

The union of the two sets is a set that will be traversed, in a for-each or 
apply-templates, in document order. Within the set, no *node* will be 
duplicated (though of course their values might).

Cheers,
Wendell
