* dict.c include/libxml/dict.h Makefile.am include/libxml/Makefile.am: new dictionary module to keep a single instance of the names used by the parser * DOCBparser.c HTMLparser.c parser.c parserInternals.c valid.c: switched all parsers to use the dictionary internally * include/libxml/HTMLparser.h include/libxml/parser.h include/libxml/parserInternals.h include/libxml/valid.h: Some of the interfaces changed as a result to receive or return "const xmlChar *" instead of "xmlChar *", this is either insignificant from an user point of view or when the returning value changed, those function are really parser internal methods that no user code should really change * doc/libxml2-api.xml doc/html/*: the API interface changed and the docs were regenerated Daniel
