cubicweb #1894929 `use_email` relation type cannot be modified [resolved]
Relation types cannot be inherited by design and we have raw permission declaration in the use_email class.
So, this is not possible to modify other use_email relations as the one found in the cube Person.
We must be more precise by replacing the relation type by an explicit definition for relation "CWUser" use_email "EmailAddress"
