/**
 * 

Axis2 states are held in two information models, called description hierarchy * and context hierarchy. Description hierarchy hold deployment configuration * and it's values does not change unless deployment configuration change * occurs where Context hierarchy hold run time information. Both hierarchies * consists four levels, Global, Service Group, Operation and Message. Please * look at "Information Model" section of "Axis2 Architecture Guide" for more * information.

*

MessageContext hold run time information about one Message invocation. It * hold reference to OperationContext, ServiceGroupContext, and Configuration * Context tied with current message. For an example if you need accesses to other * messages of the current invocation, you can get to them via OperationContext. * Addition to class attributes define in Message context, message context stores * the information as name value pairs. Those name value pairs,and class attributes * tweak the execution behavior of message context and some of them can be find in * org.apache.axis2.Constants class. (TODO we should provide list of supported * options). You may set them at any level of context hierarchy and they will * affect invocations related to their child elements.
