Yes, but the inheritance should work as well if we want to suggest
customizing only the "base face".

:inherit was not a topic in the discussions I participated.  I saw a
post a while back of somebody porting it to XEmacs but don't know if
it was checked in.  At least in XEmacs 21.4.17 I could not find it and
doubt that it will make it to the 21.4 series.  So we cannot rely on
it being present.

That's why I put it into perspective in the next sentence. (c:

Well, yes.  But you cannot really hide faces from a user.  Once he is
doing `M-x customize-apropos RET font-latex RET' he'll be presented
by the full glory of titling faces.  Not to mention XEmacs users in
case we cannot get inheritance to work.

Yes, right after you asked. (c;
