That would be an interesting addition, and would fit well with image formats
that support true variable transparency such as PNG and JPiG. Once could do
interesting things with this and negative margins. Transparency would be more
useful on foreground properties, but certainly it would be nice to set a tint
of a particular color by having the background of an element in the
full-strength color with say 90% transparency.

One would probably need a default value of 0% transparency for backwards

Yep ;-) the quickness of the hand deceives the text editor. Several people
spotted this, and it has now been fixed. Thanks - the more folk that read and
comment on the spec, the better it gets.
