SYSML17 — Stereotype Rate extends ObjectNode in the XMI, but not in the abstract syntax in the specification

According to figure 11.8, the stereotype Rate extends UML4SysML::Parameter and UML4SysML::ActivityEdge.

In SysML.xmi, you can find a third extension of UML4SysML::ObjectNode. The Association Ends section in the specification also lists the ObjectNode extension:

Association Ends
• base_ActivityEdge : ActivityEdge [0..1]
• base_ObjectNode : ObjectNode [0..1]
• base_Parameter : Parameter [0..1]

The diagram table in the activity chapter provides a concrete syntax for object nodes with stereotype Rate applied.

Besides that, the extension of ObjectNode is not mentioned in the specification.

If it is correct, that Rate extends ObjectNode:

• Add extension in figure 11.8.
• Provide semantic

If it is not correct:

• Remove extension from XMI and association ends section
• Remove concrete syntax from diagram table
