Metadata isn't meant to  be directly read by users, but by their tools. For
example, if the claim is in metadata I can search for "pages that claim to
meet WCAG double A", with a metadata-aware search engine. (This is a much
more explicit search than the "claims which have the conformance logo
somewhere" which is used at the moment). If we use EARL (a small metadata
vocabulary) I can even look for "things where the claim to meet WCAG is made
by something/someone other than bobby, unless it is Bobby in combination with
SomeFictionalTool", and other very specific searches.

It can also be used by repair tools of various types. For example, an
EARL-aware editor can find out that there is a particular problem in meeting
a checkpoint, and fix it or guide the author to fixing it. Alternatively, a
"fix the world" tool can go out and find pages with a aparticular type of
problem, publish a repair and some metadata pointing to it, and smart
browsers can add the repair to the content before presenting it to the end
user.

This doesn't prevent there being an icon, it just relies on the fact that
metadata claims are much clearer about what they mean to make less work for
people and more work for machines.

           I'm a bit confused as to how conformance is reported or asserted?

           If it is inserted as metadata, how is the information provided to
  the user? By reading the source view of a page? If the information isn't
  provided to the user, for whom is it intended?
