Which CURIE specification should one build on?

Dear RDFa working group members,

CURIEs are specified as a part of RDFa Core, but there is also an older 
standalone document at http://www.w3.org/TR/curie/.

We are specifying a language (DOL = Distributed Ontology Language; see 
http://ontolog.cim3.net/cgi-bin/wiki.pl?OntoIOp), in which we would like 
to adopt CURIEs, and we are starting to implement support for them.

On which CURIE specification should we build?  I noticed that the two 
specifications slightly differ.

RDFa Core says

(1) reference   ::=   ( ipath-absolute / ipath-rootless / ipath-empty )
                      [ "?" iquery ] [ "#" ifragment ] (as defined in 

… whereas the standalone CURIE specification says

(2) reference   :=   irelative-ref (as defined in IRI)

I think that (2) would allow to interpret scheme://authority/ as a CURIE 
with prefix scheme:, whereas it would not be a CURIE wrt. (1).

Of course, we are not interested in such cases of CURIEs, but I was just 
trying to find out the difference, and to see if it is relevant.

What would you recommend?

Cheers, and thanks,
