[xml] Ability to plug in schema validation on top libxml2 SAX parser

[Sarmishtha Bhattacharya <sarmishtha bhattacharya gmail com>]

Hi,

My question is about schema validation with libxml2 sax parser.
Is it possible to get schema validation done with a sax parser in single parse i.e. when the xml is parsed at that
same time the schema validation also takes place. I do not want to build a tree build after the parsing, i.e. i want
to retain the streaming model of sax parser.

Thanks,
Sarmishtha
