there is no formal W3C Best Practice, ie, in the sense of a requirement. But, as RaphaŽl answered you, the practice until now was indeed to favour '#' for small(er) vocabularies. 

Putting my SW Activity Lead's hat *down* for now:

I must also say that setting up and maintaining a '#' vocabulary under /ns is really easy (you give me one file in, say, turtle or RDF/XML, maybe in RDFa+HTML, and that is it), whereas setting up a '/' approach is certainly more convoluted. My *personal* favourite is certainly a '#' in this case, also to be in line with the other, similar vocabularies.

I cannot judge how widespread the usage of this vocabulary is and any change is certainly a pain. I think it is worthwhile asking the bulk of the implementers whether a change would really be a big problem for them. Put it another way: this is probably the last moment when such a change can still be envisaged... As Bob Morris says in another mail, any choice made now will stick, and has to be 100% stable thereafter.
