Re: [classad-users] Ranks and Requirements

[Alain Roy <roy@xxxxxxxxxxx>]

1. There MUST exist a REQUIREMENT and RANK attribute in both classads
 - What happens when there is no requirement attribute, does it default 
to true or does the match fail
 - What happens when there is no RANK attribute
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.)
