MH-C-EXTENSION
MH-C-EXTENSION
The MH-C-EXTENSION class allows all 1988 extensions (even unrecognized
extensions) to be made available at the GPI’s external interface. However, explicit GPI
support is limited to a subset of actively supported extensions.
The GPI explicitly supports the following subset of the 1988 X.400 extensions:
Table 3-16

An integer is used to denote standard forms of extended processing, an object identifier to denote proprietary
forms. Only an integer is permitted upon entry to an ADMD, and only an integer is present upon exit from
an ADMD.

The value for MH-T-EXTENSION-VALUE shall follow the BER. The MH-T-EXTENSION-VALUE
attribute must be present when the MH-C-EXTENSION object is included as an attribute of the MH-C-OR-
NAME object.
