This Method is called whenever an Attribute has been reached that makes use of the defined NamespaceURI. The type-parameter is the current Interpreter-Model at the time the Attribute was reached.
Note: This Method is only called in case the Element this Attribute is belonging to does not itself use a Namespace. In that case, only the processElement-Method belonging to that Namespace is called.
@param attribute The Attribute to process.
@param type The Interpreter Type the given Element belongs to.
