Also, the 'mark' properties seem to be redundant with using @media
speech with :before/:after. Claudio, do you remember why it was added?
h1 {mark-before: "section"}
p {mark-before: attr(id) }
vs
@media speech {
h1:before { content: "section"; }
p:before { content: attr(id); }
}

If I understand correctly, the purpose of SSML's "mark" element [1] is
two-fold:
(1) provide a destination 'anchor' in the text flow, for the speech
synthesizer / processor to address (similar to <a name="link_target"/>
in XHTML).
(2) raise an event when a named "mark" is encountered (trigger
asynchronous notification when reaching a pre-authored point in the
text/audio flow).
Now, to me this functionality isn't of stylistic nature. I think this
feature allows authors to define actual *data* (i.e. it does not
provide a mean to encode presentational instructions for existing
data). I am therefore in favor to remove the "mark" property from the
CSS3-Speech Working Draft.
