As one of those DCMI guys who talked to Ivan in Singapore, I'd just like
to endorse Ivan's point here.

Also it applies to other (non-DCMI owned) existing X/HTML profiles that
use a similar convention: I'm thinking particularly of Ian Davis'
"Embedded/Embeddable RDF" profile

http://purl.org/NET/erdf/profile

which I believe Ian designed to be compatible with the DCMI convention
(or at least it was one consideration in his design), see

http://research.talis.com/2005/erdf/wiki/Main/RdfInHtml

Though eRDF supports the use of either a hyphen or a period as the
separator in its "prefixed names" e.g. it supports @rel values such as

<link rel="foaf.maker" href="#ian" />

or

<link rel="foaf-maker" href="#ian" />
