Information on DTD (Document Type Definition)

A DTD (Document Type Definition) specifies the tags and associated attributes that are permitted in an associated XML or SGML document. In XML, the DTD is part of the document prolog. The DTD may reside within the XML document. Alternatively, the DTD 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 DTD, using XML schema instead. XML schema are seen as providing a more flexible means for specifying the grammar of a class of XML documents.
