  Does not match the behaviour of a pristine 2.6.19 setup here:

paphio:~/XML -> /usr/bin/xmllint tst.xml
<?xml version="1.0"?>
<tests xmlns="http://css.example.net/"; xmlns:test="http://css.example.net/";>
 <testA attribute="pass" test:attribute="fail">This should be green.</testA>
 <testB attribute="fail" test:attribute="pass">This should be green.</testB>
</tests>
paphio:~/XML -> /usr/bin/xmllint --version
/usr/bin/xmllint: using libxml version 20619
   compiled with: DTDValid FTP HTTP HTML C14N Catalog XPath XPointer XInclude Iconv Unicode Regexps Automata 
Schemas Modules
paphio:~/XML ->

  I can't reproduce your problem and I'm 100% sure xmllint uses xmlReadFile
i.e. the exact same API in that case.

paphio:~/XML -> gdb xmllint

  Please follow the guidelines for reporting bugs as much as possible,

if we can't reproduce or understand what's happening we can't help and
this just raises frustration.
