SACM21 — Replace "that" with "whether"?

p38, 11.13, Attributes: If "isCounter" seems to be set to false then stating that "a flag indicating that the AssertedRelationship counters its declared purposes" seems to be controversial, although I understand that the "false" is a default value. I think, adding "that whether the AssertedRelationship counters" is more clear. E.g. in 11.10 at a similar case, it writes "indicating the state ..." which was more clear.

Whether for that

The observation is correct - replacing "That" with "Whether" in Section 11.13
