Should this be formalized in the spec?

In 11.1.1, in the description of the values of the 'overflow' property, make the following changes: : scroll : This value indicates that the content is clipped and that if the : user agent uses a scrolling mechanism that is visible on the : screen (such as a scroll bar or a panner), that mechanism should : be displayed for a box whether or not any of its content is : clipped. This avoids any problem with scrollbars appearing and : disappearing in a dynamic environment. When this value is : specified and the target medium is 'print', overflowing content : may be printed. <ins>When used on table boxes, this value has the : same meaning as 'visible'.</ins> : auto : The behavior of the 'auto' value is user agent-dependent, but : should cause a scrolling mechanism to be provided for overflowing : boxes. <ins>When used on table boxes, this value has the same : meaning as 'visible'.</ins> [1] http://lists.w3.org/Archives/Public/www-style/2012Sep/0231.html [2] http://lists.w3.org/Archives/Public/www-style/2012Aug/0308.html 73755 8 antonsforums 2012-09-13 10:01:06 +0000 The errata document contains provisional wording added before the resolution described in Comment 7 was reached: http://www.w3.org/Style/css2-updates/REC-CSS2-20110607-errata.html#s.11.1.1a The provisional wording should be replaced with the wording from the resolution. Also, the first clause of the provisional wording ("On a table element ('display: table'), 'overflow' applies to the table box (i.e., not the table wrapper box)") should be removed since it is not directly related to this issue, and in any case is being handled separately in Bug 17122 (see Comment no.6 therein). 1167 2012-08-07 08:25:44 +0000 2012-08-07 08:25:44 +0000 Test to illustrate whether
