[Dime] Diameter Group: Type?

[Erez Nassimi <[e-mail]>]

To whom it may concern:
======================

Dealing with the Diameter standard for more than 2 years, I always had the following question, I never dared to ask. But even after 2 years, I do not seem to have a good answer for it:

In RFC 3588, section 4.2 - AVP Data Formats, "Grouped" is defined as a "basic type". Doesn't it make more sense to set a flag for Grouped AVP in flags section? Group may be basic but it is not a real type. It's just an indication of a complex data structure.

If "Grouped" is defined as a flag, it will simplify any parser's work - and performance is such a rare resource.

Thanks in advance,
