[csswg-drafts] [css-round-display] more details needed about border boundary

frivoal has just created a new issue for

== [css-round-display] more details needed about border boundary ==
Some comments I made in an old mail have yet to be addressed. Most of 
that mail has, but not all, so I'm bring back the rest here, with some
 phrasing tweaks to match the fact that the spec has evolved since. I 
am posting these multiple comments in one issues as they are related, 
but feel free to split them into multiple issues if that makes them 
easier to address.

I am not sure I understand how "border-boundary: parent" works. Is it 
to be used to fit the border inside the parent element's shape inside?
 If yes, I think you need to explain this better, and explicitly 
mention shape-inside (and probably shape-padding as well). If it means
 something else, could you explain what? I think using the parent's 
shape-inside is useful, so if that's not what your value does, then we
 should add one more value for that.

You need to give more details about how border-boundary works when the
 border is not uniform (different border styles, width, or colors for 
top/right/bottom/left borders).

---

You also need to define whether border-boundary is a purely visual 
effect, or whether it affects layout, and if so, how. I don't think it
 should.

You have an informative note that says:
> If the value of border-boundary is parent or display, border lines 
of the element are actually just a visual effect. It triggers a layout
 for rendering in a general way, but in the above cases 
(border-boundary: parent|display), the layout doesn’t occur and it 
only draws the border lines inward from the containing block’s 
borders. With this situation, the borders might hide contents around 
the display edge. 

The first and last sentence indicate that this does not affect layout.
 This needs to be normative text, not informative.

I do not understand the second sentence.
