Do we have a commit hash for this? Also v0.9.2? The profiles spec is a
crock and the version depends on the specific profile - for example
there's new tags as of last week with 0.5 in them... The original profiles
are ratified, so if this definition is in there, please cite that
instead of a "random" version.

Cheers,
Conor.
