Per discussion on the call regarding relationship cardinality.
ServiceDescCompositeComprisedOfServiceDesc is currently many to many. The reasoning for this is that at design time, a child descriptor could be related to 0 or more parents at a given moment (maybe a child was created bottom up before the parent). Similarly, the parent composite descriptor may have been created first, and some time later related to the child - hence many to many.
ServiceCompositeInstanceHasServiceInstance is 1 to 1..*. On the runtime side, the parent composite instance must have at least one child (1..*), and the child must have exactly one parent (1).
Certainly open to different views.

Regarding attachment, a stereotype is needed, and a description

Association "ServiceDescriptorMadeAvailableAsServiceInstance" which is redundant has been removed according to Xu and Kevin' suggestion.
