This is the reason why (most of the) XML parser implementations do not support XML Namespaces by default, to handle the validation of XML documents with namespaces correctly it is therefore necessary to configure the underlying parsers to provide support for XML Namespaces.At one extreme, the DPH was assumed to be a web designer accustomed to writing CGI scripts without any formal training in programming, who was going to hack it together in a weekend.
XML documents are made up of storage units called entities, which contain either parsed or unparsed data.
Parsed data is made up of characters, some of which form character data, and some of which form markup.
Markup encodes a description of the document's storage layout and logical structure.
XML provides a mechanism to impose constraints on the storage layout and logical structure.

An XML schema is compiled into an annotated automaton encoding, which includes a parsing table for structural information and annotation for type information.The data is in the encoding of the entity which contains the text.The exact interpretation of this requirement varied from person to person.The input document contains an extra attribute which has not been defined in the XML Schema, this shows that the XML Schema has been used for the validation.The middle ground was a smart grad student with a couple of weeks.In most Java applets and applications, XML should not be the central feature; instead, XML is the means to another end, such as loading configuration information, reading meta-data, or parsing transactions.
