I've tweaked the text in 
http://dvcs.w3.org/hg/prov/raw-file/tip/paq/provenance-access.html#third-party-services:

[[
The mechanisms for provenance discovery described above have all assumed the 
provenance URI is being supplied by the provider of the original resource. 
Where provenance information is provided by a third party without any 
cooperation from the original resource provider, the provenance link cannot be 
provided through the same channels as the original resource, and a different 
approach must be considered.
