[OSM-talk] "proprietary" keys and values, machine readable vs. humans

Looking at the fantastic taginfo reports [1] I noticed some tags that
link presumably proprietary databases to OSM from inside the OSM-db:
e.g. this one: http://taginfo.openstreetmap.org/keys/%25kml%3Aguid#values
with values like:
{a2ec06ed-792a-4495-9218-8b2a394c4163}

I wonder if this kind of tagging should be tolerated. In the wiki I
found no documentation regarding this tag, and therefore this data
seems unusable for most mappers.

There are other tags with similar values which are much more in use already:
http://taginfo.openstreetmap.org/keys/import_uuid#values
http://taginfo.openstreetmap.org/keys/uuid%3Abuilding#values
...
the concept seems to be documented here:
http://wiki.openstreetmap.org/wiki/Proposed_Features/UUID

cheers,
Martin
