Strings with discriminated records

[NiGHTS <nights@unku.us>]

I know that Ada Strings are an unconstrained type, and so you can't use them in records. But if a discriminated record is being passed a String parameter which is then being assigned to a String object in a record, the string is being constrained at the instantiation of the record. So shouldn't the compiler allow this configuration since it has enough information to allocate the memory required for the record?

Either way, considering this unfortunate Ada limitation, is there a workaround that can assign a string's default value on a record using a discriminant? Is there a way to do this with Fixed or bounded strings?

Thank you for your help!
