Yes, sorry for the confusion. The emphasis is on that the current behavior is
kind of a single relation, and the current proposal is about allowing multiple
relations. In case the anchor is a plain paragraph, then this means the page
text area (which doesn't include margins).

Thanks for noticing this. I would propose to ignore this property when in the
web layout, just like how increasing e.g. the left page margin has no effect
to the web layout, either.

> Perhaps the description can use a table (similar to Table 17) to describe the reference base for the different cases.

I think this will make sense to do if further, more complex relations are
considered, but for the current proposal, I think we can avoid it, since the
two cases just boil down to "existing behavior" vs "entire page".

Makes sense to me.

Did you meant "when style:rel-width-rel/height-rel is missing and
style:rel-width/height is set"? In that case, yes, I agree. The text already
implicitly proposes that in case style:rel-with/height-rel is missing or it's
specified, but the value is "paragraph", that is the same behavior; but
marking it as default explicitly is OK with me.
