Have you looked at the error log of the exception?

  >>> from lxml.etree import XML, XMLSchema
  >>> try:
  ...   XMLSchema(XML("<honk xmlns='http://www.w3.org/2001/XMLSchema'/>"))
  ... except Exception, e:
  ...   print e.error_log
  <string>:0:ERROR:SCHEMASP:SCHEMAP_NOT_SCHEMA: The XML document '(null)' is
not a schema document.


I assume the reported errors here are more telling if you pass a real schema
document, though.
