Re: [PROV-AQ] Multiple anchors and provenance-URIs

Sorry, the first examples should be

> Link: http://example.org/example.provn; rel="
> http://www.w3.org/ns/prov#hasProvenance"; anchor="
> http://example.org/example.html", http://example.org/example2.provn; rel="
> http://www.w3.org/ns/prov#hasProvenance"; anchor="
> http://example.org/example.jpg"
>
and

> Link: http://example.org/example.provn; rel="
> http://www.w3.org/ns/prov#hasProvenance"; anchor="
> http://example.org/example.html#section1",
> http://example.org/example2.provn; rel="
> http://www.w3.org/ns/prov#hasProvenance"; anchor="
> http://example.org/example.html#section2"
>
of course.

The question remains the same :)
