[simple-ruby] Normativeness

[r12a]

The document will be published as a Note, so there is iiuc no normative aspect to the document.

Therefore we should remove the statements about normativeness from the start of sections 2 and 4, and collapse the references into a single section.

On the one hand, you're right. On the other hand, it seemed useful to me to distinguish between the body of the text that describes the logic, and pieces of commentary about it. The normative/non-normative distinction offered by respec (and implied in notes) seemed right for that.

I could removed the informativeness statements in section 2 and 4, but the notes would remain "non-normative", and I think the reference section would therefore not be collapsed.

It should be possible to retain a distinction between different types of text without using the normative/non-normative terminology. I don't think that's appropriate here.
