- [Instructor] Let's take a look at the basic syntax…and content of a DTD file.…DTDs contain markup declarations…that define document content.…In other words, they lay down the rules…for what an XML document that uses that DTD…can and cannot contain.…DTDs can specify a variety of document content rules…involving elements, attributes, entities,…notations, processing instructions, comments,…and parameter entity references.…In other words, DTDs can specify…just about every single kind of XML file content type…that we looked at earlier in the course.…
Now, those last five,…from entities down through parameter entity references,…are pretty fairly advanced.…So for the rest of this chapter,…I'm only going to focus on DTDs…that define elements and attributes…because those are by far the most common examples…you're going to find when you're working with DTDs.…If you want, of course, you can head over to the W3C website…and learn all you could ever want to know about DTDs.…But I'm going to keep this as simple as I can…and just focus on elements and attributes.…
