keep-with-next on fo:table-row

[Vincent Hennebert <vi...@anyware-tech.com>]

Dear XSL Editors,

as fo:table-row does not generate any area, the text in section 4.8, 
“Keeps and Breaks” of the XSL-FO 1.1 Recommendation can’t be interpreted  
as is for this element.
The question is: if keep-with-next is set on fo:table-row, shall we 
consider that this is equivalent to setting keep-with-next on the last 
child block of /every/ cell ending on this row? In which case the first 
illustration below would not be acceptable.

Or can we consider that this is as if keep-with-next were set on every 
fo:table-cell element ending on the row (although keeps don’t apply to 
fo:table-cell). Then the first illustration below would be acceptable 
as, although it would be empty, cell 2.1 would still generate an area on 
the second page.

Illustration:
  <fo:table-row keep-with-next="always">
    <fo:table-cell>
      <fo:block>Cell 1.1 Line 1</fo:block>
      <fo:block>Cell 1.1 Line 2</fo:block>
      <fo:block>Cell 1.1 Line 3</fo:block>
    </fo:table-cell>
    <fo:table-cell>
      <fo:block>Cell 1.2 Line 1</fo:block>
      <fo:block>Cell 1.2 Line 2</fo:block>
    </fo:table-cell>
  </fo:table-row>
  <fo:table-row>
    <fo:table-cell>
      <fo:block>Cell 2.1 Line 1</fo:block>
      <fo:block>Cell 2.1 Line 2</fo:block>
    </fo:table-cell>
    <fo:table-cell>
      <fo:block>Cell 2.2 Line 1</fo:block>
      <fo:block>Cell 2.2 Line 2</fo:block>
    </fo:table-cell>
  </fo:table-row>

So is the following rendering correct:
  _____________________________________
  |                 |                 |
  | Cell 1.1 Line 1 | Cell 1.2 Line 1 |
  | Cell 1.1 Line 2 | Cell 1.2 Line 2 |

 --------------------------------------- Page break

  | Cell 1.1 Line 3 |                 |
  |_________________|_________________|
  |                 |                 |
  | Cell 2.1 Line 1 | Cell 2.2 Line 1 |
  | Cell 2.1 Line 2 | Cell 2.2 Line 2 |
  |_________________|_________________|


or can it only be like the following:
  _____________________________________
  |                 |                 |
  | Cell 1.1 Line 1 | Cell 1.2 Line 1 |

 --------------------------------------- Page break

  | Cell 1.1 Line 2 | Cell 1.2 Line 2 |
  | Cell 1.1 Line 3 |                 |
  |_________________|_________________|
  |                 |                 |
  | Cell 2.1 Line 1 | Cell 2.2 Line 1 |
  | Cell 2.1 Line 2 | Cell 2.2 Line 2 |
  |_________________|_________________|


Thanks,
