DTD means: Document Type Definition, you use it to validate that your XML file has the elements that you define in your DTD. Is like a dictionary. Supose that you make a java program that parses XML files, and you need the value of specific elements, but you don�t write the xml file, that�s the job of other people in your company, so giving them a DTD you ensure that the syntaxis of the xml they gave to you for parsing them with your java program doesn�t have mistakes.

XML is the data and DTD is the meta-data. DTD is a blueprint of an XML document and the document is sometimes called 'an instance' of the DTD. I should point out here, that DTD is a cryptic and an old standard which is becoming unpopular because of its limitations. It is going to get replaced by another metadata schema called 'XML Schema'. I have no clue though, about 'dtf'. Anyone?
