--- Comment #6 from Anton P <antonsforums@yahoo.co.uk> 2012-08-03 15:42:16 UTC ---
The WG resolved[1] to accept the clarification given in Comment 5.

Hence the changes which were resolved upon to address this issue are as
follows.


Add, as the first sentence of 9.4.2 (Inline formatting contexts), the 
following sentence:

   | An inline formatting context is established by a block
   | container box that contains no block-level boxes.

In 9.4 (Normal flow), replace:

   # Boxes in the normal flow belong to a formatting context, which may
   # be block or inline, but not both simultaneously. Block-level boxes
   # participate in a block formatting context. Inline-level boxes
   # participate in an inline formatting context.

with:

   | Boxes in the normal flow belong to a formatting context, which in
   | CSS21 may be block, inline or table. In future levels of CSS, other
   | types of formatting context will be introduced. Block-level boxes
   | participate in a block formatting context. Inline-level boxes
   | participate in an inline formatting context. Table formatting
   | contexts are described in the chapter on _tables_.

In 17.4 (Tables in the visual formatting model), replace:

   # [...] The table wrapper box establishes a block formatting context.
   # [...]

with:

   # [...] The table wrapper box establishes a block formatting context,
   # and the table box establishes a table formatting context. [...]

In 17.5 (Visual layout of table contents), replace:

   # Internal table elements generate rectangular boxes with content and
   # borders. Cells have padding as well. Internal table elements do not
   # have margins.

with:

   # Internal table elements generate rectangular boxes which
   # participate in the table formatting context established by the
   # table box. These boxes have content and borders, and cells have
   # padding as well. Internal table elements do not have margins.
