Beyond the SGML DTD
Link to this resource This short article outlines the confusion caused by the dual role of SGML and XML DTDs: grammars for the purpose of lexical parsing and schemas for the purpose of semantic validation.  | This is an email posting originally sent to the W3C XML Working Group and which was subsequently expanded to several XML Conference papers (XML 97 and XML Europe 98). An unofficial version of the latter is available at <a href="http://www.ecs.soton.ac.uk/~lac/XMLEurope98/DTDsToSchemas.html">http://www.ecs.soton.ac.uk/~lac/XMLEurope98/DTDsToSchemas.html</a>. |  |
