Xen Domain Configuration File Support Document

I completed the first draft of the Xen Configuration File support document and posted it on Xen.org on the Support pages.

This document contains a complete list of all the options available for configuring a new domain during its creation. Several examples are also presented to give the reader some basic ideas of what is commonly used in standard configuration files.

As this is a community effort, I expect to see the document grow as people submit new examples and changes to ensure it remains relevant as the Xen product line moves forward.
