OPTIONS, TITLE, PROPERTY for sure.  But as I said, someone else may
actually want them to indent, so making sure they don't drop their
font-lock-properties when indented is a better idea.

Yes, but I'm not sure it is fully up to the task yet.  But it ought to
be, since there is no point in defining the syntax of the same piece of
Org in more than one place.

That too.  Although as you note, this is fraught with peril.  But if
we'd see it through, then the result would be a lot less troublesome to
maintain.  Look at all the places in org.el where a match for headline
tags is constructed for instance…

Please see

http://thread.gmane.org/gmane.emacs.orgmode/69065/focus=71563

for a patch that attempts to implement some of this for node properties.
It doesn't yet do away with the regex in org.el since there's no obvious
convention for org-element to produce match data that can be used by the
caller -- but if there was, then the regex could move into org-element
I'd think.
