File Format Description

Text file that specifies elements and attributes used in an XML, SGML, HTML, or XHTML document; can also define the ordering and nesting for elements and their attributes; commonly referenced within Web pages using a URL.

DTD files are also used to validate whether a file represents a valid document. For example, before parsing an XML file, a program may first validate the markup declarations using a DTD file to make sure that the XML can be parsed properly.
