Walter:
The rule wording in BIRD154.1 is too rigid and limiting.
I would accept: "All entries in List_Typ shall be unique."
Example:
(List_Type "case1" "case2" "case3" "case4")
(Type Boolean)
(List True False False True)
This should be legal because you might want to correlate
this parameter with another parameter that describes the
same cases. This is not confusing. Some vendors
may want to do this.
The rule in BIRD154.1 requires too many checks. This
delays the parser development for an optional convenience
at the expense of other technical features that the user
community really needs.
So I strongly advocate the relaxation of the rule to the above
rule, which is easy to check.

Bob,
I want to keep my wording. It is important that if two values in List are
the same they have the same List_Tip value and if two values in List_Tip are
the same they have the same List value. Anything else would be totally
confusing to a user.

I would like this rule relaxed to a suggestion:
From
All entries in List_Tip shall be unique, except that if two entries in List
are the same, then the corresponding List_Tip entries must also be the same.
To
All entries in List_Tip should be unique, but if two entries in List are the
same, then the corresponding List_Tip entries can be the same.
That way, we do not have to check this in the parser and we can allow
(List 2 1 2 3 4 5)
(List_Typ "default_val" "val1" "val2" "val3" "val4" "val5")
or other equalities where the List_Typ entries might be different for the
same values.
I want to simplify parser checking and especially comparison checking within
the
List for all Types. By making this rule a suggestion, we do not have to
check it.
In practice, this will not be a problem for developers who use List_Type.

All,
Enclosed is IBIS 151.1 for review. The major change is changing Labels in
List parameters to List_Tip.
I plan on formally submitting this on Thrusday.
