[DFXP LC Comment] color space

Hello public-tt,

In 8.3.2 <color>
http://www.w3.org/TR/2005/WD-ttaf1-dfxp-20050321/#style-value-color

a) what is the color space for the RGB values (I expect it is sRGB, but
the spec does not say so)
b) Do rgba values represent premultiplied values or not?
c) Is the opacity channel linear, or not?
d) What color space is used for compositing of two rgba values?

Also, in section 8.3.12 <namedColor>
the same comment applies (I assume the answers are the same).
