I believe that the W3C should make an official property set for CSS.  The
CSS format lends itself nicely to the grove data model.  To get the ball
rolling I wrote a draft property set this evening.  Comments are
welcome.

     CSS1 Property Set DRAFT 
     By: Russell O'Connor

     This document is PUBLIC DOMAIN.

     Available at 
     <URL:http://www.undergrad.math.uwaterloo.ca/%7Eroconnor/hi2pscss.sgml>.

     This is my first stab at a Property Set for CSS1.  I'm sure that someone 
     who knows more about Property Sets than I do can improve upon this.  I 
     should also note that this is NOT a complete property set.  A complete 
     property set should be made for a final document.

     Modeled after the SGML property set document and based on Appendix B of 
     Cascading Style Sheets, level 1 
     <URL:http://www.w3.org/pub/WWW/TR/REC-CSS1#appendix-b>

<!DOCTYPE propset
   PUBLIC "ISO/IEC 10744:1997//DTD Property Set//EN"
[

<!-- I don't know if this is right.  I don't know anything about notations. 
     The W3C probably should have a FPI for CSS.

<!NOTATION CSS SYSTEM "http://www.w3.org/pub/WWW/TR/REC-CSS1">

<propset nsd=CSS>
<desc>
Defines the classes and properties to be used in the construction of
groves from the parsing of CSS documents.

<!--
     Modules should be made to separate the important aspects of CSS from the 
     full information available to the parser.  For this draft I have no modules
     and have no classes for irrelevant information such as comments etc. 
     Because of this, this is NOT a complete property set.

<classdef rcsnm=cssdoc appnm="css document">
<desc>
A CSS document.  The root of the grove.

<propdef subnode rcsnm=imports appnm="imported rules" nodelist ac=import>

<propdef subnode rcsnm=rules nodelist ac=rule>

<classdef rcsnm=import appnm="imported at-rule">

<propdef rcsnm=file appnm="file name" string>
<desc>
The file name of the imported style sheet.
<when>
A string is used instead of a URL.

<propdef subnode rcsnm=cssurl node ac=cssurl>
<desc>
The URL of the imported style sheet.

A URL is used instead of a string.

<classdef rcsnm=cssurl>

<propdef rcsnm=url string>

<!-- is the AC attribute allowed and proper for urefnodes? -->
<propdef urefnode rcsnm=cssdoc appnm="css document" fullnm="imported css

<classdef rcsnm=rule>

<propdef subnode rcsnm=selects appnm=selectors nodelist ac=selector>

acnmprop=prop>

<classdef rcsnm=selector>

<propdef subnode rcsnm=smslcts appnm="simple selectors" nodelist ac=smslct>
<note>
I consider a pseudo element a simple selector.  I consider a pseudo element to
stand on it's own separate from it's parent element.  A pseudo element must
be the last element in the list of simple selectors if it is in the list at
all.

<classdef rcsnm=smslct appnm="simple selector">

<propdef rcsnm=name string>
<desc>
The name is the generic identifier of an element, or the name of a pseudo
element.

<when>

<propdef rcsnm=psdclass appnm="pseudo class" string>

<classdef rcsnm=decl appnm=declaration>

<propdef rcsnm=prop appnm=property string>
<desc>

<!-- should this be divided into further nodes? -->
<propdef rcsnm=expr appnm=expression string>
