Re: FW: @rel type 'describedby'

Dear Miss Cotton,

Following our e-mail exchange and some feedback from Julian Reschke 
(cc'd here) I have been working on some edits to the POWDER 
specification that will, I hope, clarify exactly what it is we're asking 
for wrt. 'describedby'.

I can't formally publish a new draft of the doc (we expect the next 
version to be the Proposed Recommendation) but I would like to share the 
expected edits with you - see [1]. The changes from the current 
published draft emphasise the ATOM Link registry as the key reference 
point and show the describedby relationship used in a sample ATOM 
document (example 4-2). Specific reference is made to the ATOM RFC and 
the registry. All changes in section 4.1 are highlighted, the last being 
at the beginning of section 4.1.4.

I hope this helps.
