I'm not sure about "just patently false", but my information was
incomplete: while *in general* I can get editor<%> and text% from mred
(mred -z if I want it at the command line), the way novel snips are
added is such that DrScheme can get them without mred getting them---
as is the case with the ProfessorJ widgets (java-interactions-box% in
particular).  It's been a few months since I played with it, so I didn't
remember all the steps in the argument, but the consensus was that this
was something wrong with how MrEd was loading the ProfJ libraries.  So
at least in some cases, some of the snips are drscheme-only.

And this is not false at all, patently or otherwise.  You've admitted
yourself that the format is not documented.  If it were, I bet I could
reverse-engineer the java-interactions-box% format without too much
