the parametric object is mentioned in the uv_mapping section of the docs:

http://wiki.povray.org/content/Documentation:Reference_Section_5.2#Supported_Objects

however in the map_type section is does not:
http://wiki.povray.org/content/Documentation:Reference_Section_5.6#The_map_type_Option

I tried map_type 8 and it parsed ok fine ... but get this I also tried 
map_type 10 then map_type 100 and those BOTH parsed as well!!!

A separate bug from what you've uncovered???

Also if someone else on the team could provide a clue as to what the 
map_type 8 narrative should say, I'll make that change.

On a separate note ... Christoph posted a fix for parametric uv_mapping 
back in June of last year, that will roll with RC4
