MDC type A Extensions

This document contains a list of all current "MDC Type A Extensions". "MDC Type A Extensions" are modifications to any of the M[UMPS] related standards that have been approved by the MDC for inclusion in the next revision of those standards.

Currently, there are two groups of MDC Type A Extensions:

Those that are included in the documents that were recently circulated as Draft Standards (Canvass Documents).
