Notation declarations are used to provide information to an XML application about the format of the document's unparsed content. Notations are used by unparsed external entities, processing instructions, and some attribute values.

Notation information is not significant to the XML parser, but it is preserved for use by the client application. The public and system identifiers are made available to the client application so that it may correctly interpret non-XML data and processing instructions.
