It looks like the mlisp.patch in the root directory of cxml is outdated. I am attaching the updated patches for xml-name-rune-p.lisp and xml-parse.lisp files. So far during my tests, the patches do not introduced any bug in other lisp implementations and make cxml runnable in mlisp. Could you consider apply this patch in the next release of cxml?
