What is a DTD file?
DTD files have multiple uses, and Document Type Definition is one of them. Read more about the other uses further down the page.
Document Type Definition File
DTD is an acronym for Document Type Definition. Files that contain the .dtd file extension are text files that specify certain elements that are used in an SGML, HTML, XHTML or XML document.
The information that is contained in the DTD files is used to define the structure of given XML data. This data may define the order and nesting of a document's elements and attributes, which are referenced within a web page or application.
The DTD file allows a computer that is receiving XML from another computer to agree on the structure of the XML data that is being transmitted, ensuring uniformity. The DTD file can also be used to determine whether or not a file represents a valid document.
