Re: [ba-unrev-talk] XHTML 1.1 and purple numbers
Interesting bit of history. As a newbie, I couldn't help but naturally
run into the "underscore problem," but quickly found the XHTML team
themselves used hyphens (e.g. "background-color" instead of
I used Chris's way of doing things by leading off the structural
statement numbers with ssn, e.g. ssn02A. In whatever software follows
Doug's Augment, this notation might be used for an easily traceable
distinction between the sid and the ssn. Of course, this will have to
pass Doug, but it seems well that the OHS/Hyperscape remain on good
footing with W3C standards in the interest of some future integration. (02)
