Existing Wording: In addition to the specializations, there is one profile on Quantity used in several resources:?

Note that the profile is different from the other specializations because it is not a type, just rules applied where the Quantity type is used.

Comment:

Please include the link to the profile. It doesn't appear to be in any of the regular profile lists.

If this isn't a real profile, please use other terminology.
