cl-xml accepts and reports:
? (in-package "XML-PARSER")
#<Package "XML-PARSER">
? *version*
"0.918+"
? (parse-document "<doc xmlns:xml='http://www.w3.org/XML/1998/namespace'/>")

i do not understand the prescription, that the "xml" prefix is, by definition,
bound to "http://www.w3.org/XML/1998/namespace"; to preclude the presense of a
binding to that effect.
furthermore, i read the recommendation as not precluding that the prefix may be
bound to anything else. whereby cl-xml also accepts
? (parse-document "<doc xmlns:xml='http://www.w3.org/XML/0000/namespace'/>")
#<DOC-NODE <no uri> #x8C88DFE>
9
?
which supports distinctions, such as
? (eq (name (root (parse-document "<xml:lang xmlns:xml='http://www.w3.org/XML/1998/namespace'/>")))
(name (root (parse-document "<xml:lang xmlns:xml='http://www.w3.org/XML/1998/namespace'/>"))))
T
v/s
? (eq (name (root (parse-document "<xml:lang xmlns:xml='http://www.w3.org/XML/1998/namespace'/>")))
(name (root (parse-document "<xml:lang xmlns:xml='http://www.w3.org/XML/0000/namespace'/>"))))
NIL
?
but i suppose opinions may differ.
