Support for Turtle in WebID

The WebID incubation effort is documented at
http://www.w3.org/wiki/WebIDand there is a discussion on the mail list
about supporting the Turtle
format. We are looking for input from members of the linked data community
generally.

Currently RDF/XML and XHTML+RDFa 1.1 are required for consumers of WebID
profiles/pages. Support for Turtle would probably be worded as a required
addition to these other formats.

The incremental cost of supporting Turtle seems fairly low, given support
for RDF/XML.

Do readers of this list foresee any significant issues with this addition?
Would you recommend this addition?

Thanks
