> The spec currently defines consumer mutability of an attribute in the attribute type definition. Questions have been raised about whether that is appropriate. Few scenarios that complicate this:
> 1) Collection type 'items' attribute may be mutable or not depending on the kind of collection.
> 2) the consumer mutability of an attribute may depend on an instance not the type. Moving this to the type necessitates unnecessary invention of additional types
> 3) the mutability of an attribute may depend on other factors such as authorization/credentials of the consumer or it may change with time (because changing the attribute value may make something else inconsistent).
> Issues 180, 196, and 199 depend on resolution of this issue.
