What about...?

    fullname=2005.*,2006.*,-2005.GroupHeader,-2006.HomePage

Seems pretty straightforward to me.  :-)

More to the point, PmWikiPhilosophy #3 applies here.  *If* 
someone comes up with a definite query (as opposed to a conjectural 
"someone might want" query) that can't be solved by one or more of 
the fullname=, trail=, and list= parameters, *then* I might see
about adjusing the syntax (most likely by using '+' signs to
indicate unions or additions.  But I don't want to spend much 
time defining and implementing a conjectural query syntax until
there's an actual problem to be solved.
