The resolution says to change the NUMBER token, but that doesn't
7971-
solve the issue with <number>, and probably breaks things
7972-
elsewhere. It is likely that the decision (to disallow spaces and
7973-
comments after the sign, like in the WD of css3-values) was
7974-
recorded incorrectly.

8267+
<blockquote>
8268+
<dl>
8269+
<dt><strong>scroll</strong> <dd>This value indicates that the
8270+
content is clipped and that if the user agent uses a scrolling
8271+
mechanism that is visible on the screen (such as a scroll bar
8272+
or a panner), that mechanism should be displayed for a box
8273+
whether or not any of its content is clipped. This avoids any
8274+
problem with scrollbars appearing and disappearing in a dynamic
8275+
environment. When this value is specified and the target
8276+
medium is 'print', overflowing content may be printed.
8277+
<ins>When used on <a href="tables.html#table-box">table

boxes,</a> this value has the same meaning as 'visible'.</ins>
8279+
8280+
<dt><strong>auto</strong> <dd>The behavior of the 'auto' value
8281+
is user agent-dependent, but should cause a scrolling mechanism
8282+
to be provided for overflowing boxes. <ins>When used on <a
