SYSML11 — Section: Annex A

In Annex A, the bdd is indicated that it can only be for blocks, pkgs, and constraint blocks. [A previous issue was raised that this list should include activities]. This list is incomplete; it should probably include all SysML-allowed stereotypes (and extensions) of class (perhaps classifier), including signal, actor, interface, etc. Even if such elements are not allowed to be model elements for the diagram, they should be explicitly allowed as elements on a bdd. Similarly the allowed elements for and on an ibd should be clarified.

Discussion:
The above reference to Annex A (Section A.1 pg 173) is not referring to model
elements that can appear on a block definition diagram, internal block diagram or
any other diagram. It is referring to the type of model element that is represented
by the frame of the diagram. As a result, this is a misinterpretation of the content.
It is felt that the description is adequately clear, so no change is required.
The type of model elements that can appear on a diagram are specified in the
applicable chapter as described in the last paragraph on pg 172 in Annex A.
Disposition: Closed, no change
