I'm puzzled here.  The syntax also allows for adding strings, which
could also be semantic (although presumably not causing problems for
screen readers unless it also was ignored by the user agent).  Are you
saying that only meaningless strings such as " " or "*#*#*#*" belong in
a content property?  (A string of "*" of course becomes semantic if used
to mark required fields or otherwise marks certain items as having a
certain property.)

Or perhaps we could think of it more like an independent clause, which
if missing does not change the meaning of a sentence but if present
enriches understanding of the sentence.

Hope this helps,
