-      Implementers of Content Negotiation by Profile need not provide systems that conform to multiple functional profiles
-      of this specification, only the functional profile(s) that are relevant to the target environment. In some
-      cases, for example the Query String Argument-relevant human browser environment, there is a choice of more than
-      one functional profile. Since all functional profiles of this specification themselves must conform to this specification, by
-      design, conformance to any functional profile guarantees conformance to the specification.

+        The functional profiles provided here are conformant with the Abstract
+        Model. Systems may implement one or more of the profiles provided in
+        this document or may develop other functional profiles that conform to
+        the abstract model. Conformance to one of the profiles provided here
+        guarantees conformance to the abstract model, but conformance can be
+        achieved with other functional profiles. Implementers of Content
+        Negotiation by Profile need not ensure systems conform to multiple
+        functional profiles of this specification, they need only conform to the
+        functional profile(s) relevant to their environment.
