My take on in-caption comments was to put them in a class and hide the
class, with the advantage of the comments being available programmatically
(you can toggle them on for editing purposes by un-hiding the class) and
requiring no additional specification, though the disadvantage that you need
a stylesheet to properly view the resulting file.  To avoid that, maybe a
separate span type would be better, analogous to the "hidden" HTML

(I don't want to restart the whole comment discussion, but it'd be
unfortunate if the desired syntax for inline comments never happens due to
being punted to v2 and then being impossible to make backwards-compatible
with v1.)
