SAX parser and afterwards the one of the Schema validator if present. Is
there a specific reason for calling the user function first? Cause i
would expect the validation callback be called first and my user
function afterwards. 

  Why ?
Actually XSD is not part of the parsing per XML-1.0 (contrary to DTD
validation) so it sounds more sensible to me to first do the parsing
steps, possibly building the data needed to then process the validation
feedback. XSD can't possibly influence parsing.
