Afaik this CSSOM clause is relatively recent and remains Editor's Draft 
material. I don't think you'll find many properties working that way across 
browsers, or strong interest in fixing existing serialization to work this
way given the compatibility risks. I don't recall any WG discussion on using 
syntax definitions to specify OM serialization. There was a brief discussion 
on the topic on this mailing list a few months ago. I'm still of the opinion 
dbaron expressed at the time [1]
