[xml] libxml parses and serializes "invalid" xml?

[Boris Erdmann <b erdmann 4commerce de>]

Hello List,

when we parse

<?xml version="1.0" encoding="iso-8859-1"?>
<root xmlns="xmlns.4commerce.de/master-namespace">
   <elt xmlns=""/>
   <bad:elt xmlns:bad=""/>
</root>

and directly serialize, we get:

<?xml version="1.0" encoding="iso-8859-1"?>
<root xmlns="xmlns.4commerce.de/master-namespace">
   <elt xmlns=""/>
   <elt xmlns:bad=""/>
</root>

Thus x -> xmlDocDumpMemory(xmlParseFile(x),.,.) is not
identitiy on semantcis of the document, since it rebinds
the second <elt> from null to master-namespace!!!

Anyway: as far as I know
(http://www.w3.org/TR/1999/REC-xml-names-19990114/#dt-NSName -
2nd definition)

<bad:elt xmlns:bad=""/> is not even allowed.

Should this generate a parser error?

Should i file a bug report?
