<para>
Provides structured access to debug, information, warning and error
messages from the libraries.  Structured information is most often
used from errors such as parsing where file or URI and line numbers
can be returned via a #raptor_locator object pointer found by
librdf_log_message_locator() on the #librdf_log_message.
