there is no separate comment list; the reference in the document for comments is the WG mailing list...

But yes, this _is_ a last call comment, though I thought it is an editorial issue.

So, to make it clear, the question is what is the effect of @prefix="a: http://a.b a: http://c.d". In my original mail I said it should be left to right. But I since seemed to remember that we decided to have it right to left, ie, in my example, the result should be a->http://a.b. I tried to find a resolution in the mail archives, but I could not. However I did find this:


which led to a discussion thread on the relative priority within a @profile. This led to this resolution:


ie, left-most declaration wins. I have not found any resolutions related to @prefix. However, based on the the resolution we have already taken for @profile I would propose to define the same order for @prefix and that should be documented in RDFa 1.1 Core
