I noticed the thread on metaDataInURI-31 a few minutes after sending the attached note on opacity, and came to exactly the same conclusion. I held off on sending a note in the interest of not unnecessarily clogging the list, presuming you all would make the connection if that's the way you wanted to handle it. One thing I would add: regardless of whether you track it as a separate issue or combined with "metaDataInURI-31", I think there are important aspects of the URI opacity issue that go beyond metadata. I would be disappointed if the opacity issue were dealt with only as a detail relating to metadata. I think it's much more fundamental than that.

I hope that for now at least we can view metaDataInURI-31 as a reasonable 'peg' to hang opacity discussions on, rather than opening a fresh issue. Anyway, thank you for your concern and interest, and I shall endeavour to make some progress on *drafting* a finding for the issue as a seed for further discussion.
