[css3-animations] Missing definition for the term "animation properties"

The term "animation properties" is not defined, and its usage appears to  
be inconsistent.

http://dev.w3.org/csswg/css3-animations/#the-animation-fill-mode-property-
"If the value for ‘animation-fill-mode’ is ‘both’, then the animation will  
follow the rules for both ‘forwards’ and ‘backwards’. That is, it will  
extend the animation properties in both directions."

Here the meaning seems to be "the properties being animated".

http://dev.w3.org/csswg/css3-animations/#the-animation-shorthand-property-
"The ‘animation’ shorthand property combines seven of the animation  
properties into a single property."

Here, the meaning is "properties whose name begins with 'animation-'".  
(There are other occurrences as well)
