This module defines annotations that can be attached to (almost) any nexml element. The markup for these annotations is like that of xml-plists, such as are used by iTunes libraries and other Mac OS X configuration files. However, this module extends on that by defining more simple types that can be used as values of the key/value pairs that comprise the annotation. In particular, the additional types are lists of atomic simple types, so that a value can be a list of integers, for example. The base type for all complexType definitions in the nexml schema. This type allows a number of special attributes:

• xml:lang - for languages codes
• xml:base - see http://www.w3.org/TR/xmlbase/
• xml:id - see http://www.w3.org/TR/xml-id/
• xml:space - for whitespace handling
• xlink:href - for links
• class - for class membership

Also see http://www.w3.org/2001/xml.xsd for more information on the xml and xlink attributes. A dictionary; a sequence of key/value pairs, where the value elements are of some type. A vector of dictionaries.
