Actually, it's more than that. Because, as you see below, for each 
property there are two URIs, a reg:name, and an rdfs:label. The "lexical 
URI" is based on the reg:name not the rdfs:label. So that makes one 
opaque identifier, one lexical identifer, and two display forms. The 
reg:name is camel case and condensed, as compared to the label, which is 
space-delimited words. Both have language designations.

The rdfs:label is written as a verb phrase, with either "has" or "is" -- 
a form that I generally find annoying in practice -- while the reg:name 
is "noun-ish." I'm sympathetic to the "has" form in some situations, 
such as when reading a triple as a statement, but the verb-enhanced form 
would seem odd on an input form, for example. Having both could be 
useful, but since RDF doesn't recognize label types it only works in a 
closed world.
