Since this link relation is based on the POWDER stuff, it is pretty

I'm (still) puzzled by the fact that the specification tries to register
a short name for use in HTML link/@rel and in Atom relations, but then
goes on defining a relation URI for use in RDF contexts --
<http://www.w3.org/TR/powder-dr/#semlink>:
"4.1.3 Semantic Linkage Using the describedby Property
We define the RDF property wdrs:describedby with a domain of
rdf:resource and a range of wdrs:Document. This is the class of POWDER
documents and is a sub class of owl:Ontology.
In formats that support RDF properties directly it is appropriate to
link a resource to a POWDER document that describes it through the
wdrs:describedby predicate rather than the describedby relationship
type. For example, a document might be part of a collection about a
particular topic described in a DR. Such a document might be annotated
using RDFa as shown in example 4-2 below.
Example 4-2: RDFa snippet using wdrs:describedby [HTML]
1 <html
2 xmlns="http://www.w3.org/1999/xhtml"; version="XHTML+RDFa 1.0"
3 xmlns:wdrs="http://www.w3.org/2007/05/powder-s#";>
4 <head>
5 <title>The English Civil War</title>
6 <link rel="wdrs:describedby"
href="http://ecw.example.org/powder1.xml"; type="text/powder+xml" />
7 </head>
8 <body>
9 …
10 <p>Charles I came to the throne believing in his
11 <a href="http://monarchy.example.org/divine_right.html";>Divine
Right</a> to rule…
12 …
13 </body>
14 </html>"
So if the URI for use as relation name in RDF is
"http://www.w3.org/2007/05/powder-s#describedby"; why not use the same
URI in Atom?
