The CSS WG published the first of a new series of working drafts, called
"CSS Image Values Module Level 3":

    http://www.w3.org/TR/2009/WD-css3-images-20090723/

The module defines the <image> type, i.e., the syntax for properties
that refer to images. (Examples of such properties are
'list-style-image' and 'background-image'.) In most (all?) cases, an
image is identified by a URL.

It also proposes a new image fallback feature, which allows an author to
specify the same image in different formats. The goal is to deal with
UAs that understand different image formats.

A scheme (URL scheme? XPointer scheme?) to refer to a small rectangle
out of a larger image may also be added to the module. This is subject
to coordination with the Media Fragments WG[1] (which has this in its
charter) and the SVG WG (SVG has such a scheme built-in[2]; it may be
enough to refer to other formats through SVG.)

Comments on the module are welcome. Please, send them to this mailing
list, <www-style@w3.org>, with a subject line that starts with
[css3-images], like the subject line of this message.
