1.8 Vendor-Extensible Fields
There are no vendor-extensible fields in the Remote Administration Protocol. The commands that the Remote Administration Protocol processes may include vendor-extensible fields such as version information and descriptive text.
This protocol uses Win32 error codes as defined in [MS-ERREF] section 2.2. Implementations SHOULD<3> reuse those values with their indicated meanings. Choosing any other value runs the risk of a collision in the future.
