Javadoc

Represents a container configuration that uses expressions in values. We use a cascading model, so you only have to specify attributes in your config that you actually want to change. String values may use expressions. The variable context defaults to the 'current' container, but parent values may be accessed through the special "parent" property. get* can take either a simple property name (foo), or an EL expression (${foo.bar}).
