We are taught for the Oral exam that the only way you can prove you took off
into legal minimums for VFR flight is to obtain a weather briefing from the
FSS or DUATS.
It is only the FSS or DUATS weather report for that time that determines if
you are legally allowed to be flying based on your restrictions, whatever
they may be.
Your local tower or TV station might tell you the weather is one thing, but
if the FSS says it isn't you could be in violation.

I don't know what kind of documentation you are looking for, but I have been
told that I will be wrong if I don't answer the question with the FAA
examiner this way.

Only a FAA or a DUATS briefing counts.

Where is that documented?

Which part? That you need a briefing, that it has to be "official" or
that FS and DUATS are the only briefings that count?

91.103 says you need a briefing and contains the catch all of "all
available information concerning that flight" which to the FAA enforcers
means weather, NOTAMs, TFRs, etc.

That's not what 91.103 says.

AIM 5-1-1 says FS or DUATS.

It suggests FSS or DUATS.

There was a proposed AC to add other services; I don't know if it was
approved.

I have seen FAA statements to that effect but only for part 91 flights.
