[postgis-devel] WKT and Wikipedia

I just came across this page:
http://en.wikipedia.org/wiki/Well-known_text

I think this page is incorrect, misleading, and contains typos.  It is 
my understanding that the OGC specs on WKT does *not* include 3D and 4D 
definitions.  It is a PostGIS extension to use Z, M, or ZM. Or am I off 
on this?
(http://portal.opengeospatial.org/files/?artifact_id=829) (section 3.2.5.2)

I don't have an account to correct this.  Does any here have one?  Do we 
care?

Should the new PostGIS docs reference such pages, or point to only the 
OGC specs?
