Paul,

What you describe means we could invent an extra markup that indicates that the content of the blank is:
- a "blank markup" that should be deleted right away on focus entry (but restored if nothing changed?)
- a "prefilled answer", for example if the server returns an answer to be revised: it should not be removed on focus entry
- a simple "measure stab" that would allow the renderer to draw the right blank size (I think ActiveMath had this for a while).

What else?
(what about something for in-browser comparison?)
And, more importantly, do we need them simultaneously?

Paul

It would be nice for a processing program interested in the meaning of the mathematics (e.g., an answer checker) to safely ignore the former but not the latter.

> Several interesting issues came up when the structure guidelines I mentioned in previous email were being developed. One of those was how to represent in MathML "blanks" that should be filled in by a student.  The main issue for the DAISY guidelines was how to let assistive technology know that something was a blank so it could be spoken appropriately, but any solution should also work for online assessment (etc) in general, not just for those using assistive technology.  To address "fill in the blanks", the MathML Working Group has come up with a draft note:

> There are several open questions (see the end of that document), and we would appreciate feedback on both those questions and on the proposal in general.  Please send comments and questions to this email list.
