Implied Group inside a Partioned Group.

Hi all,
I am using Mercator 1.4.2 (Quite old now!!) I have a doubt. Can I take it as a rule of thumb that an implied group inside an Partioned group is always mandatory even if the group is declared as optional.

Suppose I have 3 groups a(1),b(1), C(C contains two groups c(0:1) and d(0:s)) all the 3 groups are implied groups. I have partioned them so that they are mutually exclucive. But I face the problem that when the Mercator starts reading the group C (which consists of two groups c and d) though I have declared the groups as conditional, if the c group alone is present in the input and d group is absent in the input it justs prompts an error that "The group d is absent and the Group C failed partioning" and exists.

Can Somebody explain this strange behaviour of Mercator.

Regards,
