I have scanned through the POWDER document yesterday and, indeed, I saw
with pleasure the usage of RDFa...

However, there is another issue that is indirectly raised by POWDER.
According tot he document, one of the ways to access a POWDER
information is to use the <link> element with the rel="powder" value.
The POWDER document does refer to the issue (to be solved) of the
extensibility of the @rel values, and whether a separate profile should
be defined for POWDER. However, this begs the question: as a Semantic
Web document, wouldn't it be better if the list of predefined RDFa
properties included the value of 'powder' from the start?

Just a question...
