I made a brief attempt to do this by putting local copies of xexpr->xml and
srep->attribute into my code.  I'm not fluent enough with mzscheme to understand
why altering the local srep->attribute (to allow non-strings) still gives the
same error.  To me, following all the unit/sig setup is a little mysterious--
it's not clear how many of the xml.ss component files I'd need to copy and
alter.
