No, this is consistent with CSS1; CSS2 just spells it out a little more
clearly. 4.5 of CSS1 includes the rule

"If the 'background' value of the 'HTML' element is different from
'transparent' then use it, else use the 'background' value of the 'BODY'
element. If the resulting value is 'transparent', the rendering is
undefined."

The intent of this is clarified in the example that follows:

"This rule allows:

  <HTML STYLE="background: url(http://style.com/marble.png)">
  <BODY STYLE="background: red">

In the example above, the canvas will be covered with "marble". The
background of the 'BODY' element (which may or may not fully cover the
canvas) will be red."

Right. In what way do the rules in 4.5 of CSS1 and 14.2 of CSS2 not achieve
the reconciliation you're looking for?

It seems to me these rules could be extended to cover those extensions, too;
though perhaps I'm overlooking something.
