[plt-scheme] Sanitizing DrScheme .scm files with XML boxes for MzScheme?
We have been discussion this issue internally for a while.
I have suffered from this XML box thing for as long as they have
existed. I created an entire Web site with it and then got stuck when
Matthew changed the format from one version to another and I
accidentally touched the site with the new version. (I needed the old
Web server for another week or so.) -- I have suffered from this for
Interaction boxes in ProfessorJ. -- For test boxes. -- And now I want
it for the wizard boxes.
So we'll do something soon -- Matthias
