[css-page-floats] Mostly editorial comments

I think most or all of these comments are editorial, so i didn't split 
them up into multiple messages.


Section 5, Deferring Floats, starts out with the assertion,
[[
A page float can be deferred to another fragmentation container than 
where the float anchor is placed.
]]

Does this mean that an implementation has the flexibility to defer 
floats, or that users can control whether floats are deferred/

I think from the following paragraph it means the latter, but then why 
is the first paragraph there?

Suggest removing the first paragraph.

"This new property is instroduced" should name the property, e.g.
"The float-defer property controls what happens when floats are 
deferred:"

The description of a negative integer value could possibly be clearer 
:-) I _think_ it's trying to say that negative values count backwards 
from the last framentainer, with -1 being the last one, -2 being the 
next-to-last, and so on. It also needs to say what happens if N is less 
than -(total number of fragmentainers + 1) and also what happens if the 
fragmentainer referred to is earlier in the document -- e.g. we're 
formatting the third fragmentainer and we get to a request to put a 
float in the 2nd fragmentainer.

In 7,

"This property pushes a float in opposite direction of the where it has 
been floated with float."
should be (i think)
"This property pushes a float in the direction opposite to which it has 
been floated with float."
but opposite could mean, up instead of down, or it could mean 
horizontally instead of vertically. The examples suggest the first of 
those meanings is intended (e.g. float: left; moves a block horizontally 
and potentially to the left, so we can only move it to the right. I 
don't understand how this would work if we move something in two 
directions at 0nce with float, as in some of the multi-column examples)

"This property can only influence a page float along an axis it has been 
floated." probably means
"This property can only influence a page float along an axis along which 
has been floated."
As written it's not a grammatical sentence I think, or at least I can't 
parse it.

Example 20:
suppose contining-block-width is 300px and pull-quote-width is 100px.
Then 50% is (300 - 100)px is 200px and moving the block by this much 
will not in fact center it. Or is the percentage applied twice/
What happens if there are two or more adjacent blocks floated and pushed 
by a percentage??

8 stacking order
We need to be able to override the float stacking order.
See attachment 1 "pagefloat01.png" -- the left-hand situation isn't 
acceptable in general.

Spanning of floats: Maybe this is specified elsewhere? See 
pagefloat02.png (attached) for examples of floated figures that (1) span 
two columns of text - not necessarily all columns if there are more than 
two - and (2) in the 2nd case, disrupt the flow of text, indicated with 
numerals in the grey boxes indicating text flow sequence.
