David,
Jumping to your second point:

In 18.352, it says:

That does not affect the validity of your first point that we leave the
behavior underdefined.
I don't remember specifically but suspect I changed the prose because a
gradient doesn't "interpolate" between two values. It represents an
interpolation between two values but that isn't the same thing. To be
fully precise, the <draw:opacity> elements contains two attributes,
draw:start and draw:end which specify the start and end values used in
an interpolation of a color gradient. But, wording it from the
perspective of the draw:start attribute the words were shifted around.
Note that the datatype does not enforce the value range given in the prose.
Hope you are looking forward to a great weekend!
