Will do.  But not for a few days.  

ACTION: Add text to Guide re disjoint classes and pointer to test.

I still think we need to actually describe the solution, not just 
point at the test -- Mike, how about putting a paragraph of 
description (take it from Ian's email or work with him to get it 
written) describing what to do - something like

"When n is large, an alternate encoding can be used.  In this case, ..."

For some reason I thought we had agreed to do this when I withdrew my 
objection to not adding allDisjoint, but I cannot find the record of 
that - so now I ask again.  Also, we should have something in Ref 
that points back to this section of Guide or has a discussion there.
