While looking at another issue I stumbled across the 'unofficial' 
keyword having been added to the 3.7.1 master branch at some point? This 
isn't the uberpov approach, but suppose it could be useful in marking 
scene files as not working with any official POV-Ray release as in:

#version unofficial 3.71;
...scene here...

Should this keyword capability be documented?

Thinking otherwise patch developers are unlikely to know about it except 
by stumbling across it as I just did.

That keyword has effectively been around for ages -- it just wasn't
syntax-highlighted.

Support for this syntax used to be mandatory in patched versions,
according to the old POV-Ray Modification License
(http://www://www.povray.org/source-license-3.6.html.

Official POV-Ray has been supporting this syntax in the sense that it
gives a special error message upon encountering `#version unofficial`.

Thanks. I now see the introduction of 'unofficial' to reservedwords.cpp 
in commit e1e7b0d (Fix GitHub issue #53. include file version...) was a 
code change in support & not a keyword addition.

I'm taking what you wrote to mean "leave 'unoffical' undocumented."
