Validation
In computing, validation is the process of checking input data to ensure that it is complete, accurate, and reasonable. In the case of markup languages like XML, it is the process of checking whether a document conforms to the rules of a particular DTD or Schema. It involves comparing the local document to an instance of the DTD or Schema which can either be held locally or referenced via the Web.
