475817 - Better documentation needed for syntax of Mozilla CSS extensions using properties

Status: RESOLVED WONTFIX

(Developer Documentation Graveyard :: Mozilla Platform, defect, P5)

Description

[Ben Lerner]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5
Build Identifier: 

A documentation & parsing question: which is the correct syntax?
a) treechildren::-moz-tree-line(selected focus)   <<-- sans comma
b) treechildren::-moz-tree-line(selected, focus)  <<-- with comma

It appears that 
(a) is correct according to the W3C spec and is accepted by Firefox, 
(b) is properly rejected by Firefox when I try it, 
(a) is recommended by https://developer.mozilla.org/en/CSS/:-moz-tree-row
(b) is recommended by http://www.xulplanet.com/tutorials/xultu/treestyle.html (linked to from the previous link),
(b) is used by e.g. AdBlock Plus.

This documentation could be improved for most of the Mozilla CSS extensions content at https://developer.mozilla.org/en/CSS_Reference/Mozilla_Extensions


Reproducible: Always
