The current text is:

"The tts:opacity attribute is used to specify a style property that  
defines the opacity (or transparency) of..."

I think that the following minor alteration removes the ambiguity due  
to the use of "or":

"The tts:opacity attribute is used to specify a style property that  
defines the opacity (or conversely, the transparency) of..."

This way, the mathematical relationship is immediately apparent and  
the reading flow is improved. To me anyway.

Yes, I scrolled-up to "2.3 Documentation Conventions" and found the  
explanation.
