[Crm-sig] ISSUE: P55 should have domain E18 Physical Thing

[Vladimir Alexiev]

I think that P55 should have the same domain as P53 (E18 Physical Thing),
and not a more specific class.
- Currently you can say "E18 Physical Thing. P53 has former or current
location" but not "E18 Physical Thing. P55 has current location".
- Looking at the class diagram, P55 excludes: Physical Feature, Site,
Man-Made Feature, Man-Made Thing, Collection.
What is the justification?
