A document (especially a DTD or entity set) can be given a public identifier which is independent of file names, etc. This identifier can be authenticated by an organisation (e.g. ISO) and can then be used anywhere to refer to that document. Example:'PUBLIC "-//IETF//DTD HTML 2.0//EN"' can be used to refer to Version 2.0 of the HTML DTD and 'PUBLIC "ISO 8879:1986//ENTITIES Added Latin 1//EN"' to the ISO entities for additional Latin charcaters-1. A strict HTML document instance should begin with a DOCTYPE like: !DOCTYPE PUBLIC "-//IETF//DTD HTML 2.0//EN";
