Bob,
"All cases 4 below are correct for List. "
How could they be?

Michael:
Good questions and many more should follow.
So, I would hold off starting to write explanations until we
have the organization nailed down. Your general question also
applies to Corner, Range, Increment, Step and maybe something
else. There are different rules and limits for Default values for each
case as to what a member of the class may mean and the limits.
All cases 4 below are correct for List. For List repeats are required,
so a new "unlisted value" (Default E) would be flagged as an error.

Arpad,
Thanks. If this is the consensus answer, we'll need to add some explanatory
text plus edit out the <typ value> mention in the List syntax definition. The
new text would state exactly what you did: if Default is not present for a
List, the first item in the list is assumed the Default value.

Mike,
The list is just a list of A, B, C, D, where "A" is the first
item in the list.
If Default is not defined, the first item will be used from the
list. I don't know why the name "typ" was given to this first
item, but that is just a bad naming convention (probably coming
from the Range, or Increment types).
Does this answer your question?
Thanks,
Arpad

(this may require cross-posting to ibis-macro)
In reviewing Section 10A in the draft 5.1 document, I have a question about the
"typ value" of a Model Specific parameter: for List, etc., must one list a
*duplicate* value for the typ value? In other words, are repeats required?
This should not be affected by the presence of "Default" (though "Default"
makes it confusing).
Here's an example in four variations. Which is correct? My own vote is for
(1) and (4) being correct. However, we only say that the Default value has to
be a member of the list, *not* that the typ value has to be a member of the
list! ("Also, if Default is specified, <value> must be a member of the set of
allowed values of the parameter. If Default is not specified, the default value
of the parameters will be the <typ> value.")
1)
(Informative_String (Usage In)(List B A B C D)(Type String)(Default B)
(Description "This is an example with a repeated item, because the first
in the list should be the Typ Value"))
2)
(Informative_String (Usage In)(List A B C D)(Type String)(Default B)
(Description "This is an example without a repeated item, because the
first in the list shouldn't have to be the Typ Value, as I have a Default
declared; but I risk declaring a typ that isn't actually in my list, if the typ
is A and the list consists only of B, C and D"))
3)
(Informative_String (Usage In)(List A B C D)(Type String)
(Description "This is an example without a repeated item, and without a
Default, I risk declaring a typ that isn't actually in my list, if the typ is A
and the list consists only of B, C and D"))
4)
(Informative_String (Usage In)(List B A B C D)(Type String)
(Description "This is an example with a repeated item, and without a
Default; this technically matches the spirit and letter of the 5.1 law"))
