  Does xsltproc show errors messages on those examples ?

  To trap error, use xsltSetGenericErrorFunc() to define your own
callback function. 
  I agree it's not a good API, an I should provide something tied to the
given transformation (and using xsltApplyStylesheetUser() should allow the
user to select its own set of call back from a provided
xsltTransformContextPtr).
