sorry for the late response.  The warnings are a cxml bug I haven't
fixed yet (sorry about that, too :-)).  Until then, my recommendation is
to use the following workaround:

(handler-bind ((warning #'muffle-warning))
  ...)

around the call to map-document to suppress the warnings and any related
performance issues.
