I'm not sure what counts as "released", but the project reported in
[1] uses cnt  via its sister "Http in RDF"[2].  They appear to use it
in a fashion rather consistently with a remark in the closing of an
issue [3] in PROV declining to make it part of PROV itself

[1] Thomas Steiner et al. "Adding Meaning to Facebook Microposts via a
Mash-up API and Tracking Its Data Provenance" http://bit.ly/UQAziR

[3] ISSUE-171: HTTP in RDF http://www.w3.org/2011/prov/track/issues/171
