I have updated the old mapping document to include Glue Schema v1.3.
    

"In some General Information Provider implementations (GIP), the
ContactString Info
attribute of the ComputingElement entity is not necessarily a GRAM URL
and may
have the form <GRAM-URL>-<VO-Name>. This form cannot be used directly as
a contact string by most Grid clients. In LCG, the Resource Broker
processes this
value so that it can be used by the standard Grid clients. In the
mapping to old
ClassAd, instead, the value is published in the form <GRAM-URL>,
irrespectively of
the GIP implementation, by comparing the value of ContactString with the
values in
the GlueCEAccessControlBaseRule (i.e., the VO names). This is important
in order
to use the Condor Matchmaking Service out-of-the-box for Resource
Selection."

Unless I'm missing the point, this is wrong. The LCG format is
<GRAM-URL>-<QUEUE-Name> (at least for LCG CEs, glite CEs don't use GRAM
at all). It happens to be the case that many sites have queues named for
VOs, but it isn't a general rule.
