In fact, for the purpose of this specification, the target URI does not necessarily have to identify a dereferencable resource (or even use a dereferencable URI scheme). Clients can treat the occurrence of a specific URI in the same way as an XML namespace URI and invoke specific behavior based on the assumption that a specific profile target URI signals that a resource representation follows a specific profile. Note that, at the same time, it is possible for profile target URIs to use dereferencable URIs and to use a representation (which is outside the scope of this specification) that represents the information about the profile in a human- or machine-readable way." cheers, dret.
