A generic mechanism for accessing collections of name/value pairs. Examples of such collections are HashMap, Properties, ServletContext. In order to add support for a new such collection type to JXPath, perform the following two steps:

1. Build an implementation of the DynamicPropertyHandler interface for the desired collection type.
2. Invoke the static method JXPathIntrospector.registerDynamicClass(class, handlerClass)

JXPath allows access to dynamic properties using these three formats:

• "myMap/myKey"
• "myMap[@name = 'myKey']"
• "myMap[name(.) = 'myKey']"
