[crm-sig] Proposals for consistency, P33,

[martin]

a) P33 used specific technique (was used by) should be subproperty of
    P12 occurred in the presence of (was present at)

(Scope note: This property describes the active or passive presence of a persistent item in an event without implying any specific role.
It connects the history of a thing with the place and date of an event. For example, an object may be the desk, now in a museum on which a treaty was signed. The presence of an immaterial thing
implies the presence of at least one of its carriers.
Examples:  Deckchair 42 (E19) was present at The sinking of the Titanic (E5))

 Reason: the specific technique participates through its carrier, as any
immaterial object can do.

b) Actor Appellation needs a specific "is identified by" property, as all
other appellations specific to a fundamental category.

best,

Martin
