[ttml1] Check dependency on CSS 3 Color

swickr has just created a new issue for https://github.com/w3c/ttml1:

== Check dependency on CSS 3 Color ==
The (normative) reference to CSS3 Color is out of date.  Noticing this led me to look at how the CSS Color reference was used.  In 8.2.13 the prose might be interpreted as an informative reference but it's not clear to me that the specification of opacity in 8.2.13 is sufficient on its own for an implementor; i.e. the CSS3 Color specification of opacity is important material for the developer.

Please clarify this dependency; if the specification of tts:opacity does depend on CSS3 Color then the reference should be updated as well.
