Up to now the common practice is whatever the LCFG configuration decided to
do :)

That's really two different kinds of question. Something like the OS name
format should be defined by the schema, but unfortunately it isn't, that's
one of the defects of the schema at the moment. It also isn't even defined
what counts as the "same" OS, i.e. should RHEL, SL, SLC3, CentOs, ... all
have the same OS name, or all different, or what?
The RunTimeEnvironment is different. As far as the schema is concerned
it's just a free text string which can be used to identify any capability
that people want. In the case of something like MPI you need to get
agreement between the users who are interested in it. However, there should
still be some way for syadmins to find out what has been agreed - like many
things, at the moment that probably means asking here! Up to now LCG hasn't
supported MPI so I don't know of a convention, although INFN has been using
it so you could ask someone there.
In fact looking at LCG now I see:
ldapsearch -x -h lcgbdii02.gridpp.rl.ac.uk -p 2170 -b o=grid | grep -i
untimeenv | grep -i mpi

so it looks like MPICH gets the vote ...
