The working group has been throwing this extended attr() syntax about in
discussions and it seems it finally got itself into a published working
draft before anyone defined it. ;-)
The proposed extended syntax of attr() is:
attr( <attribute name>, <type> )
...so, for example, the idea is that one could do something like:
plank { height: attr(y, cm); width: attr(x, cm);
background: attr(tone, color) attr(texture, url); }
This syntax solves the problem with allowing attr() everywhere, where
because you don't have any typing information from the document tree, you
cannot determine what "55" or "#123456" or "wood" means.
