What is a DTD file?

A DTD file is a text file that specifies elements and attributes used in an XML, SGML, HTML, or XHTML document. It can also define the ordering and nesting for elements and their attributes. DTD files are commonly referenced within webpages using a URL.

More Information

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.
