Usually, a condition of type "exn" has "message" (string),
"location" (symbol, name of the function) and "arguments"
properties. The latter holds a list of arguments (usually the
arguments passed to "error"). I recommend to invoke
m-p-c with "... 'arguments (list port)...", or even add a "port"
property to the ssax condition (that might be better, I'd say).
