I would add reasons:

* Feedback from those using linked data in the enterprise that using
RDF/XML confuses developers who put their XML heads on and
mis-apply ideas like XSLT and the DOM instead of thinking in the RDF model.

* Turtle allows if necessary relative URIs in namespaces, which can
make the engineering easier when for example you have a server proxied
behind another, or a file which is used in file: space and served in http: space.

* (Turtle does not imply full N3, but in the future there is an upgrade path
if there are situations in which you need to have graphs within graphs,
in future specs, like for serializing proofs or dumps of provenance information, etc.)

I'd strongly support turtle being a MUST for consumers, and SHOULD use for providers, with RDF/XML required for consumers and deprecated for providers.

I don't know a library which supports RDF/XML but not turtle. The rdflib.js library
(the one Tabulator uses) supports both, but currently only turtle works in the Node.js port which I have been using for a command line test harness as node.js 0.6.5 didn't have a suitable XML library available at the time.
