  So far, I can't reproduce this with just xmllint, I will have to
look more closely at their code and data to see if it exhibit some
funky behaviour. This may be due to the fact that they use the interfaces
based on SAX v1 instead on SAX v2 with 2.6, getting the most out of 
the new code requires to change the API used slighly, I need to write
docs about this.
