=Attributes= ClientRequest depends on a number of attributes for its information.

Version
The Version attribute is simply a string of the version of the client, release.major.minor style (such as 0.3.0).

CustomMessageId
The CustomRequestId is an enumeration of the custom request. This needs more documentation!
