I'll assume your answer means all pages in: 

  (2005.* UNION 2006.*) MINUS *.GroupHeader MINUS *.HomePage
  
...because even your wording was ambiguous, it could very
well have been interpreted as, all pages in: 
  
  2005.* UNION (2006.* MINUS *.GroupHeader MINUS *.HomePage)

...I know, I know, I'm being picky.


  So then it becomes impossible to create ceratin exact sets.  
I was hoping I could get it to instead mean:

  (2005.* MINUS *.GroupHeader) UNION (2006.* MINUS *.HomePage)

I don't see a way for someone to define something like that?
