*
* This file contains the interface for the XVersion component. This
* component represents a version ID.  It is encapsulated within a component
* so that it's type and implementation can change without affecting users of
* it.
*
* The version is formatted as X.YYZ where X = 0 - 9, Y = 00 - 99, Z = a - z
* X is the major revision, YY is the minor revision, and Z is the
* compatability revision.
*
* Packed versions are also utilized for the configuration ROM such that
* memory is minimized. A packed version consumes only 16 bits and is
* formatted as follows.
*
* <pre>
* Revision                  Range       Bit Positions
*
* Major Revision            0 - 9       Bits 15 - 12
* Minor Revision            0 - 99      Bits 11 - 5
* Compatability Revision    a - z       Bits 4 - 0
* </pre>
