Information on Document Type Definition

A Document Type Definition specifies the tags and associated attributes that are permitted in an associated XML or SGML document. In XML, the Document Type Definition is part of the document prolog. The Document Type Definition may reside within the XML document. Alternatively, the Document Type Definition may lie in a separate file that is identified using a URI.
     In recent times, document designers have started to move away from the use of Document Type Definition, using XML schema instead. XML schema are seen as providing a more flexible means for specifying the grammar of a class of XML documents.
