Markup Languages play a very important role in encoding and standardizing information that is shared over the web. XML (Extensible Markup Language), being one of those languages, provides a set of rules to encode data in the document which is both human as well as machine-readable.
For this, XML uses a unique specification norm to define the structure of a document which is called a Document Type Definition (DTD). In this article, we have covered every minute detail about DTD and its components. So, without any delay, let us delve deep into the DTD Components.
