Two quick questions DH,
Did you check the commentary?
Did you go to aws.org under the ...I'll have to look it up and edit this, but find the drop down for 'Technical Inquiries'. They have it divided into sections and you can see if there is anything already asked and answered for D1.2 to help you out.
Great, okay, go to the main website, go to 'committees and sections', on the drop down menu go to 'technical committees', then on the left go down to 'Get Available Code Interpretations'. BUT, there isn't one for D1.2. I searched the whole thing and couldn't find anything. So, no answer there.
You are right, but, our committees are just human too. Sometimes, when you are the one doing the research and composing of an article, code, etc it just seems so obvious to you that you don't even consider that others aren't going to get it. And there is no perfect language. Individuals being what they are for education, experience, language skills, analytical abilities, etc there will always be room for disagreement and difference of opinion.
I'll try a couple of more search parameters and see if I can find the one you asked about.
