DTD stands for Document Type Definition. The DTD is most commonly used in web pages. By declaring a DTD at the top of the page, the browser is given a "Rosetta Stone" telling it how to render the page.
The use of internal markers has long existed in binary files. A GIF file, for instance, may be either the 1989 format, which allows (among other things) animation, or the original 1987 format, which was slightly smaller. Label a 1989-format GIF file with a name ending in JPG, and virtually any browser will see that the first six bytes are the ASCII characters "GIF89A" and will render it correctly.
The use of DTD allows similar behavior with ASCII files. Because the DTD is an external URL, browsers do not need to download the same information over and over, and because it's not internal to the browser, browsers are able to deal with new file formats that did not exist when the browser was initially released.
