Abstract Abstract
Many protocols make use of points of extensibility that use constants Many protocols make use of points of extensibility that use constants
to identify various protocol parameters. To ensure that the values to identify various protocol parameters. To ensure that the values
used in these fields do not have conflicting uses, and to promote used in these fields do not have conflicting uses, and to promote
interoperability, their allocation is often coordinated by a central interoperability, their allocation is often coordinated by a central
