+ * Revision 1.4 2000/05/20 20:31:40 gerd
+ * Big change: Added support for various encodings of the

+ * Initial revision.
+ *
+ *
+ * ======================================================================
+ *
+ * DERIVED FROM REVISION 1.3 of markup_lexer_types_shadow.mli
+ *
+ * Revision 1.3 1999/08/31 19:13:31 gerd
+ * Added checks on proper PE nesting. The idea is that tokens such
+ * as Decl_element and Decl_rangle carry an entity ID with them. This ID
+ * is simply an object of type < >, i.e. you can only test on identity.
+ * The lexer always produces tokens with a dummy ID because it does not
+ * know which entity is the current one. The entity layer replaces the dummy
+ * ID with the actual ID. The parser checks that the IDs of pairs such as
+ * Decl_element and Decl_rangle are the same; otherwise a Validation_error
+ * is produced.
+ *
+ * Revision 1.2 1999/08/10 21:35:09 gerd
+ * The XML/encoding declaration at the beginning of entities is
+ * evaluated. In particular, entities have now a method "xml_declaration"
+ * which returns the name/value pairs of such a declaration. The "encoding"
+ * setting is interpreted by the entity itself; "version", and "standalone"
+ * are interpreted by Markup_yacc.parse_document_entity. Other settings
+ * are ignored (this does not conform to the standard; the standard prescribes
+ * that "version" MUST be given in the declaration of document; "standalone"
+ * and "encoding" CAN be declared; no other settings are allowed).
+ * TODO: The user should be warned if the standard is not exactly
+ * fulfilled. -- The "standalone" property is not checked yet.
+ *
+ * Revision 1.1 1999/08/10 00:35:51 gerd
+ * Initial revision.
