-(* ======================================================================
- * History:
- *
- * $Log$
- * Revision 1.1 2001/10/24 15:33:16 sacerdot
- * New procedure to create metadata committed and old procedure removed.
- * The new procedure is based on ocaml code and builds metadata for both
- * forward and backward pointers. The old one was based on a stylesheet.
- *
- * Revision 1.16 2001/07/01 09:46:40 gerd
- * Fix: resolve_read_url_channel does not use the base_url if
- * the current URL is already absolute
- *
- * Revision 1.15 2001/07/01 08:35:23 gerd
- * Instead of the ~auto_close argument, there is now a
- * ~close argument for several functions/classes. This allows some
- * additional action when the resolver is closed.
- *
- * Revision 1.14 2001/06/14 23:28:02 gerd
- * Fix: class combine works now with private IDs.
- *
- * Revision 1.13 2001/04/22 14:16:48 gerd
- * resolve_as_file: you can map private IDs to arbitrary channels.
- * resolve_read_url_channel: changed type of the channel_of_url
- * argument (ext_id is also passed)
- * More examples and documentation.
- *
- * Revision 1.12 2001/04/21 17:40:48 gerd
- * Bugfix in 'combine'
- *
- * Revision 1.11 2001/04/03 20:22:44 gerd
- * New resolvers for catalogs of PUBLIC and SYSTEM IDs.
- * Improved "combine": PUBLIC and SYSTEM IDs are handled
- * separately.
- * Rewritten from_file: Is now a simple application of the
- * Pxp_reader classes and functions. (The same has still to be done
- * for from_channel!)
- *
- * Revision 1.10 2001/02/01 20:38:49 gerd
- * New support for PUBLIC identifiers.
- *
- * Revision 1.9 2000/08/14 22:24:55 gerd
- * Moved the module Pxp_encoding to the netstring package under
- * the new name Netconversion.
- *
- * Revision 1.8 2000/07/16 18:31:09 gerd
- * The exception Illegal_character has been dropped.
- *
- * Revision 1.7 2000/07/09 15:32:01 gerd
- * Fix in resolve_this_channel, resolve_this_string
- *
- * Revision 1.6 2000/07/09 01:05:33 gerd
- * New methode 'close_all' that closes the clones, too.
- *
- * Revision 1.5 2000/07/08 16:24:56 gerd
- * Introduced the exception 'Not_resolvable' to indicate that
- * 'combine' should not try the next resolver of the list.
- *
- * Revision 1.4 2000/07/06 23:04:46 gerd
- * Quick fix for 'combine': The active resolver is "prefered",
- * but the other resolvers are also used.
- *
- * Revision 1.3 2000/07/06 21:43:45 gerd
- * Fix: Public(_,name) is now treated as System(name) if
- * name is non-empty.
- *
- * Revision 1.2 2000/07/04 22:13:30 gerd
- * Implemented the new API rev. 1.2 of pxp_reader.mli.
- *
- * Revision 1.1 2000/05/29 23:48:38 gerd
- * Changed module names:
- * Markup_aux into Pxp_aux
- * Markup_codewriter into Pxp_codewriter
- * Markup_document into Pxp_document
- * Markup_dtd into Pxp_dtd
- * Markup_entity into Pxp_entity
- * Markup_lexer_types into Pxp_lexer_types
- * Markup_reader into Pxp_reader
- * Markup_types into Pxp_types
- * Markup_yacc into Pxp_yacc
- * See directory "compatibility" for (almost) compatible wrappers emulating
- * Markup_document, Markup_dtd, Markup_reader, Markup_types, and Markup_yacc.
- *
- * ======================================================================
- * Old logs from markup_reader.ml:
- *
- * Revision 1.3 2000/05/29 21:14:57 gerd
- * Changed the type 'encoding' into a polymorphic variant.
- *
- * Revision 1.2 2000/05/20 20:31:40 gerd
- * Big change: Added support for various encodings of the
- * internal representation.
- *
- * Revision 1.1 2000/03/13 23:41:44 gerd
- * Initial revision; this code was formerly part of Markup_entity.
