Introduction to DTD |
|
Applications can share XML data using a document structure. The document structure specifies in advance the kinds of XML data elements, element formats, and attributes to expect during the data interchange. Therefore, sharing a common document structure ensures that applications are sharing correct data in the correct format. An XML document is a valid document if it conforms to a specified document structure. The structure of an XML document can be specified in a Document Type Definition (DTD). A DTD is a collection of markup declarations that define the legal building blocks of an XML document.
