As experience is gained with a published information module, it may be desirable to revise that information module.
To begin, the invocation of the MODULE-IDENTITY macro should be updated to include information about the revision. Usually, this consists of updating the LAST-UPDATED clause and adding a pair of REVISION and DESCRIPTION clauses. However, other existing clauses in the invocation may be updated.
Note that the module's label (e.g., "FIZBIN-MIB" from the example in Section 5.8), is not changed when the information module is revised.
