Packages are a way to group actions, results, result types, interceptors, and interceptor-stacks into a logical configuration unit. Conceptually, packages are similiar to objects in that they can be extended and have individual parts that can be overridden by "sub" packages.
The package element has one required attribute, name, which acts as the key for later reference to the package. The extends attribute is optional and allows one package to inherit the configuration of one or more previous packages - including all interceptor, interceptor-stack, and action configurations.
Note that the configuration file is processed sequentially down the document, so the package referenced by an "extends" should be defined above the package which extends it.
The optional abstract attribute creates a base package that can omit the action configuration.
