  Yes there is SAX based validation support. If you run xmllint with
the options "--sax --schemas schemas_file instance(s)" then it will do
just that, that's part of the regression tests.
  You can just look at how it is done in xmllint.c , see testSAX()
around the code calling xmlSchemaValidateStream().
  In general I try to not promote SAX parsing because it is complex,
and hard to debug, and the last thing I need is beginners trapped into
SAX callback debugging asking for help on this list, so I don't put out
standalone SAX examples, if you use SAX you will have to be able to
find your way around, this is not for beginners.
  There is also support for Schemas at the Reader API which is a quite
simpler streaming API, but yes SAX support is there too.
