Clarifying ambigious usage of the "Sender" association type between various entities
Created by: mukil
As it looks to me the Assoc Type Sender (composite, childTopic=E-Mail Address) was used to express at least the following relations:
- a "Contact" (=_Person_ or Institution) relating somehow to a User Account
- a "Contact" (=_Person_ or Institution) for a somehow related Signature
- a "Contact" (=_Person_ or Institution) as Sender of a Mail (possibly duplicating? the Composition of "From" to "Mail")
