In addition to Nick's excellent response, I want to point out that new 
ClassAds does not require you to use Requirements of Rank attributes. It 
happens that the function we use for matching does use it, but you can 
easily construct similar classads and do whatever you like.

For instance, you could do a three way match by constructing the 
appropriate ClassAd that defines other1 and other2 instead of just 
other. (Not that other1 and other2 are good names.)
In that case, I would assume I will have to write my customized bind() 
and match() functions. I get it !

Thanks for your responses.
