most efficient way to check for a group of tags?

2005-03-02 13:37:51
I've got a template that needs to know the if it
contains only 1 of a specific group of tags when it's
within a "content" tag, and I've got this condition to
do this:

count(ancestor::content[1]/child::*[self:tag1 or
self:tag2 or self:tag3 ....]) = 1

Now I need to check for about 15 different tags; is
there a more efficient way to do this sort of check?
