Should Viewpoints specify applicable scopes?

[haarer]

A viewpoint showing a decomposition can have views, which may be used to show only a partly or a full decomposition.
It should be possible without defining different viewpoints, e.g. for full or partly decomposition.
We could state this in the applicability section of a viewpoint doc.

is it necessary to capture the scope of a view formally ? It could be an attribute of the diagram, since they are stereotyped anyway.
