+      A class providing location information through an

+      <tt>sax:register-sax-parser</tt> to pass their parser instance to
+      the handler.  The easiest way to receive sax parsers instances is

+      A mixin for sax handler classes that records the sax handler

+      are provided that allow those functions to be called directly on
+      the sax-parser-mixin.
