RE: Splitting background-position in two different attributes

There are other concerns before you even get to that.

Things like...

div {
 background-image: url(a.png), url(b.png), url(c.png), url(d.png);
 background-position-x: 1px, 2px, 3px;
 background-position-y: 10%, 20%, 30%, 40%, 50%;
 background-repeat: no-repeat, repeat, repeat-y;
}

(a) What should an OM query for background-position return?  (I think empty string because it's not constructible.)
(b) What should the used value for the x dimension of background-position be for the 4th image? (I think 1px, just like its repeat value is no-repeat.)

There are a myriad of cases like these.  We've addressed many of them in IE9 and have work to do (IE10+) on others.  Whether the WG will agree with our assessments and approach will be fodder for many fun discussions, I'm sure.

Also, I'd like to see a proposal that actually specifies the interaction with the extended background-position syntax that was introduced in L3 and the logical-keyword set that we will presumably introduce in L4.
