This object reports the MIB's own revision number as a fixed 4-character string, where the characters represent the high and low digits of the major version followed by the high and low digits of the minor version. An administrator reads it to confirm exactly which version of this EMC gateway MIB definition the device implements, which matters when cross-checking against vendor documentation or scripts written against a specific schema version. A value like "0100" would indicate major revision 01 and minor revision 00.
