The implementation of XML Schemas Part 1 is work in progress.

AKAIK there is no workaround for this issue. The schema processor does 
not handle <any> and <anyAttribute> yet. I'm currently working on 
<anyAttribute>. This will introduce handling of wildcards, so I hope it 
will be of some use for validation and derivation (this is the annoying 
part of the whole story) of <any> as well.
If you don't need it urgently: you could wait or help implementing, if 
you have resources left; if you need it urgently: I can only repeat 
Igor's words: you could use an other processor like Xerces, or, if you 
want to stay with libxml2, you could use Relax NG as the schema type.
