In Sec. 7.1 of H.225.0 the following paragraph appears shortly before
the table:

"Endpoints not supporting Q.931 shifted code sets shall ignore all Q.931
messages using such methods."

Was this not supposed to read:

"Endpoints not supporting Q.931 shifted code sets shall ignore all IEs
using such methods."

Background: the latter is the practice in ISDN land.  The typical use of
shifted code sets in North America is for the end-to-end transport of
display information (e.g. caller's name and number).  Code set 5
(national information) is used for the purpose.
