Re: equations

/ "Chris Chiasson" <> was heard to say:
| As you mentioned in the other email, since math isn't a child of
| mediaobject, two equations must be created. Since two equations are
| created, the author needs two ids to validate. If there are two ids to
| reference, the author needs two xrefs.

Why not do it this way:

<equation xml:id="myeqn" condition="mathmlok">
...mathml...
</equation>
<equation xml:id="myeqn" condition="nomathml">
...notmathml...
</equation>

Then you can just use <xref linkend="myeqn"/>. You can't validate the
un-profiled version which is kind of a drag, but since you don't plan
to publish the unprofiled version, it's probably safer to validate the
profiled version(s).

I believe that's the intended semantic of equation without a title.
But the stylesheets might not yet have caught up with that understanding.
