This is not correct. Pyxie uses pyexpat directly. xmln and
xmlv are separate, utility programs, intended for command
line use in pipeline XML processing.

You cannot use canonical XML to achieve what PYX achieves. PYX
is a line oriented, utterly trivial representation of
the logical structure of an XML instance. Canonical XML
is neither of these things.
