Experiment with porting SGML to YAP, and trying to preserve SWI code as much

as possible.

+TODO LIST:
+
+	* Handling of external entities (both param and normal) in Prolog
+	* Check ID/IDREF
+	* Donot use quoted values for tag identifications.  Right now the
+	  following leads to bad error handling:
+
+		<tag name="value>
+	* Allow for (a,b) as attribute-type (name-group)
+	* Handle source-info in included SYSTEM entities
+
+UNICODE:
+
+	* Started full unicode support under the CVS branch XML_UNICODE.
+	* Old version only allows for unicide in CDATA (attribute values
+	  and element content)
+	* New adds throughout: element-names, tags, filenames, etc.
+	
+	ISSUES:
+		- Port to Windows
+		- Testing
+			- File-entities
+		- Leak setting filename using istrdup() in sgml2pl
+		- Verify performance.  Optimise.
+		- Own character classification and conversion
+			- Copy from Prolog?
