[css3-speech] LC comment: no longdesc for the aural formatting model diagram

aloha!

the diagram in section 4 has no equivalent provided; neither @longdesc
or a span marked with @aria-describedby to provide a verbose description
of the diagram

it is possible that applying @aria-describedby to the first paragraph
of the section might provide a sufficient descriptor for the diagram
-- i don't know because i myself am blind...

if adding ARIA markup isn't an option, please consdier changing
the @alt text for the diagram to indicate that the diagram it illustrates
is described in the preceding paragraph...

thanks, gregory.
