I'm happy with that as far as it goes, but (on reflection) I think there's 
another angle that might usefully be added, relating to privacy concerns 
(another staple of IETF security considerations).  The wording will 
probably need polishing...

RDF is designed to support inference over possibly large 
datasets.  Therefore, one should be careful about publishing even slightly 
private information in RDF form, as in conjunction with snippets of RDF 
information from other sources it may be possible to infer significant 
privacy-infringing information.
