Term Structure and Day Count Convention

[aodetti]

Hi guys,

I would like to tell you something about the behaviour of TermStructures
classes.

I don't understand why I should give the constructor of term structures
a Day Count Convention.

In my opinion a term structure is an object independent of Day Count Convention.
(I NEED Convention to create the term strucuture, I mean Rate Helpers need
Day COunt Convention!)

The Discount Factors for a given date does not change with conventions.
So I could imagine that

- TermStrucuture does not have a DayCount Convention
- DiscountFactor method does not need a DayCount Convention
- the function for a specific Rate DOES need this convention

any idea about that?

bye
