The logo testing (as it used to be called, but that also now seems out of date) is mentioned at the first link, Step 4 - where you are supposed to submit samples of the encoded material to Dolby for approval - this includes packaging (for logo placement & correct Trademark usage) and the actual disc so that they can decode and analyze the bitstream to ensure compliance.
The content owners will certainly need a TMA to release a DVD with Dolby Digital marked on the packaging in any way at all - but the rules seem to keep changing and it is kind of tough keeping up with it all.
Getting the TMA is free - unless you include the cost of the En/Decoders.
IMHO it is well worth doing.
