The LDraw.org Standards Committee (LSC) has recently discussed the issue of
embedded POV-Ray code in Official Parts Library files.  After careful
consideration and with inputs from leading non-LSC members, most notably Lars
Hassing and Chris Dee, we have agreed that the inclusion of this code is
undesirable.

Our main reasoning behind this conclusion is outlined below is that the
inclusion of POV-Ray code locks the Official Library into a standard beyond  the
control of the LSC. The intermixing of language formats creates backwards
compatiblity issues that are too large to ignore.

Could you give a bit more info on the compatability issues (or a pointer to
where they're discussed)?

Basically,

The POV team controls the syntax, functionality, and implementation of the
POV-Ray Scene Description Language (P-R SDL) format.  While the POV Team is very
good at maintaining backwards compatibility, they have in the past change the
functionality of or depreciated some the commands. Since we, the LSC, have no
input on how or when changes to this format occur this creates the potential for
a discongruity between the LDraw Official Parts Library and the P-R SDL.  This
discongruity could effect 1 part or every part in the library leading to a
massive effort to bring the Official Library back into alignment with the P-R
SDL.  This best solution to prevent this and to allow for POV Code descriptions
of the Official Library is to disallow the inclusion of P-R SDL code in the
Official Library and establish a separate library for the P-R SDL code.
