I would tend to agree. But I think that it might very well be appropriate
for the commentary to contain something like

	- Note that the above wording implies that if a class has any data
	  members, then ... (some guarantee about pointer comparisons).

In other words, requirements for data members (or such-like) could be implicit
rather than explicit in the ARM.
