All I'm saying is that it would have occurred to me much sooner than it appear has done to you, that the motivation for other posters making their observations was based upon the assumption that this was a small part of a larger spec. The fact that it is the spec should not have been lost on you. I'm stunned that you couldn't see that and made numerous posts inviting further comments before bothering to point it out. Frankly, it is you who encouraged further discussion around it!!!! It also quite odd that you agreed with the earlier posts (in #9) even when (you alone!!!) knew that that was the entire brief.

It was never a straightforward question, btw, as you assert above. How can it have been when people pointed out valid observations (within the context of what they knew), that you agreed with and then invited further discussion about before revealing the most pertinent piece of information that was hitherto missing! Am I the only one sighing heavily right now?
