Here is a list of errors and typos in section 12
(http://www.w3.org/TR/PR-CSS2/generate.html) of the proposed recommendation.
Oh, and at the bottom is an idea for CSS3.

***********************************************

From section 12.1:
>P.note:before { content: "Note: ";
>                border: solid green}
>
>would cause a solid green border to be rendered
>around the entire paragraph, including the initial string.

I disagree. To get the effect described one would use

P.note:before { content: "Note: "; }
P.note        { border: solid green; }

***********************************************

Row 4 of the table above 12.4.2
There is a "<" in the source which should be 'escaped' as &lt;

***********************************************

The comment above 12.5.1 illustrates a major drawback of the counter
scheme - what if you do not control all of the stylesheets? Is there a way
around this? (I can't think of one offhand)

The comment in question is:
> The 'counter-reset' property follows the cascading
> rules. Thus, due to cascading, the following stylesheet:
>
> H1 {counter-reset: section -1}
> H1 {counter-reset: imagenum 99}
>
> will only reset 'imagenum'. To reset both counters,
> they have to be specified together:
>
> H1 {counter-reset: section -1 imagenum 99}

***********************************************

The second example in section 12.4 has the rather exotic style sheet:
> LI:before

>               display: marker;
>               content: "(" numeric(counter) ")";
>               width: 6em;
>               text-align: center;
>           }
...which should actually be:
 LI:before

               display: marker;
               content: "(" counter(counter) ")";
                          /*^^^^^^^*/
               counter-increment: counter;
             /*^^^^^^^^^^^^^^^^^^^^^^^^^^^*/
               width: 6em;
               text-align: center;
           }

***********************************************

The fourth example also uses the mysterious "numeric()" function (which
should be changed to counter()).

***********************************************

Will CSS3 offer a way of refering to another elements counter?

I need to mention an image's caption. This is how I would mark it up (I've
used an imaginary XML language since I can't see of any way of doing this in
HTML4):

<IMG SRC="apicture.png" ID=thepic/>
<PARA>
Here we discuss the points raised in <REF REFID=thepic/>. There is nothing
special to mention.
</PARA>

Using the following style sheet:

PARA { display: block; }

IMG { float: left; background: attr(SRC);
      counter-increment: figures;
      padding: 10px; }
IMG[SRC=apicture.png] { width: 200px; height: 200px; }
IMG:before { content: "Fig " counter(figures); }

REF:before { content: "figure " proxycounter(attr(REFID), figures); }

/* proxycounter is the only addition here, all the rest is valid with
CSS2-PR */

Would hopefully make something looking like:

+--------+ Here we
|*Fig 1 *| discuss
|***    *| the points
|****  **| raised in
|********| figure 1.
+--------+ There is
 nothing special to
 mention.
