[specs notes] all-once

https://css-print-lab.github.io/specs/notes-in-css-print/#the-'element()'-value

In the specs, we proposed the all-once argument for element(), but we see that this creates inconsistencies:

ISSUE: In [css-gcpm-3](https://www.w3.org/TR/css-gcpm-3/), the default value of the second argument of the element() function is first. However, when notes are created from the note()function, this should be the value all-onceby default. How do you indicate this?

ISSUE: If the other arguments of the function element() are declared (first, first-except, last, start), what does that do for the note elements?

ISSUE:If too complicated, why not simply remove all-once from element() when used with notes?

I feel like this confuses our proposal. Shouldn't we just remove it and say that when element() inherits from note(), it simply doesn’t need a second argument?

I’d better force users to use all-once explicitly if they want to display all notes. It’s a bit stupid, but it’s really more simple as it doesn’t create special cases, and not really long to write as we’ll often have only a few @note-area blocks to configure. Implementations will also be easier.

[JulieBlanc]

In that case, are we explicitly saying that the other arguments don't apply to the case of notes?

Yes, we can say that they can apply, but that they’re not really useful.

While doing a recap to make sure i got it right, i got this

Repeated
first show only the first note
start show the entry value unless a note is the first element on the page
last show the exit value
first-except show the first note on all the subsequent pages.

Not repeated
all-once:  show all the note on the page, only on the page they appear. (this will be affected by the note-policyat some point.

Yes, that’s it.

Actually, even these values could be interesting. With start, you could define a note at the beginning of a chapter to see it displayed on all the pages of the chapter (something like "this chapter is not normative" in a spec), and an empty note on chapters where there’s no note to be displayed.

to build on that and #5

you could have start once so you don’t need to have an empty note after to make it disappear.

i agree with the needs of an explicit value, and that first is the default.
