[occi-wg] Regarding Mixin relation and "accumulation" of attributes

Andy, you asked about whether a Mixin related to another Mixin will
inherit the attributes.

Please look at OCCI Core page 9:

"Mixin Relationships A Mixin instance MAY be related to another Mixin
instance for type classification
purposes. For example a set of operating system templates, implemented as
Mixin instances, could be related
to an “OS-template” Mixin in order to help identification.

Attributes and Actions defined by different Mixin instances are combined
when Mixin relationships are present.
^^^^^^^^^^^

Therefore a resource instance associated with a particular Mixin will
receive the additional capabilities defined
by any related Mixin instances as well as those defined by the Mixin
associated."

Does this cover what you were after? Maybe it is unclear that
"capabilities" refer to attributes as well?

regards, Ralf
