Here is what I propose for floats in multicol:

1) In [multicol] spec, remove special treatment for overflow of floats. Overflow floats should be clipped to the column exactly as any other kind of overflow would. This way, content that was initially designed for single-column layout has same behavior.

2) Leave definition of floats that intrude across columns to GCPM [2]. In fact, page floats as currently defined in GCPM are powerful enough to work as shown in [1].

There have been no implementations of intrusions, so it seems best to removed them when going to CR. Answer on www-style

In section 4, Column gaps and rules [1]:

"Column rules are only drawn between columns that have content."

Assuming column 2's entire content did not fit e.g. an image and needs to overflow to the next page, I assume column 2 is considered to have content in this case.

I just noticed that there is still an example (example VI) in the non-normative section 1 that we forgot to delete, when we removed the 'column-break-*' properties from the draft. editorial fixed

The title is still "CSS3 module: Multi-column layout"

Hadn't the WG decided to adopt consistent naming and in particular to avoid saying CSS3?

If yes, it should be called "CSS Multi-column Layout Module" or "CSS Multi-column Layout Module Level 3" (although I guess that Level 3 is only for features that did exist in level 2)

New title: CSS Multi-column Layout Module howcome Giovanni howcome
About column-rule-color: Why UAs are required only to support CSS2 colors? If the goal is to avoid the burden of hsl / rgba / SVG colors, shouldn't that be delegated to a reduced profile? The CSS WG chose to point to refer to CSS 2.1 instead of creating a reduced profile. This was accepted by Giovanni. howcome Giovanni howcome
About column breaks: At the beginning of section 5, replace desrciption with description editorial howcome Giovanni howcome
About column breaks: Is it possible to avoid a column break while still allow a page break? Is the intended effect like:
----------------------------------
| a bcd efg hij |                |
| lmn opq rst u |                |

/ page break, but content remains 
  in the same column /

| rst uvw xyz ab|                |
| cde fgh ijk l |                |
----------------------------------

About column breaks: What about margin and collapsing of them? If you're delegating all (not just properties) to css3-page, you should say that explicitly. howcome Giovanni howcome
About overflow inside and outside the multicolum element: you should insert some examples of non-floated, overflowing, clipped element (maybe inlines with long words) howcome Giovanni howcome
About overflow inside and outside the multicolum element: what happens if a non-floated element overflows vertically? Is it still clipped regardless of overflow? Can implementations put scrollbars, if overflow asks so? howcome Giovanni howcome
About overflow inside and outside the multicolum element: what happens if Example XVIII has an element that floats on the right? Is the element clipped (showing only the right part), does the element intrude (ignoring the side of the float), does overflow apply? intrusion has been removed howcome Giovanni howcome
About overflow inside and outside the multicolum element: if there are more columns than available, are scrollbars rendered when overflow:auto / scroll? howcome Giovanni howcome
Section conformance names a "column-grid-image", but no definition is provided in the document. a spurious reference to 'column-gap-image' has been removed howcome Giovanni howcome
