Yes, which is generated programatically now.  

Although there are no language bindings to this, you can see how to do
it in the libraptor manual page or
  http://librdf.org/raptor/libraptor.html
by looking for "features_enumerate".  There are APIs to get and set
parser and xml writer features.  In redland terms, what is important to
know are the URIs (from the libraptor man page):
 [[
  Raptor features have URIs that are constructed from the URI  
  http://feature.librdf.org/raptor- and the name so for example  
  feature scanForRDF has URI http://feature.librdf.org/raptor-scanForRDF
]]

then you can use the redland parser method
  int librdf_parser_set_feature (librdf_parser* parser,
                                 librdf_uri* feature,
                                 librdf_node* value);

Most of the values are boolean/ints but the raptor man page explains
more in raptor_set_feature as well as the rapper help page.
