The last paragraph on page 11-10 in the 1988 stable aggreements says:

================
ALPHABETS
T.61 Strings used as attribute values shall only encode graphic
characters and space. They must not contain formatting characters
(such as subscript) or other control characters.
================

Does it mean that only the "elementary graphic characters" (T.61 2.13)
are allowed? But what about the "composite graphic characters"? They
are graphic characters, but we need the shift-characters to change the
character set. The end result is a "graphic character" still.

Another somewhat related question is:

Is a T.61 with a number of "unnecessary" shift controls equal to the
same string without the unnecessary ones? E.g. would the following
strings be equal:

F r e d SHIFT-LOCK-1 SHIFT-LOCK-1 F l i n t a
F r e d SHIFT-LOCK-1 F l i n t a
