You've been reading the spec very carefully.. well done!
Luckily, this is not an error, it is intentional.

The content sets are used to describe the content models
of other elements.

Some elements are so tightly bound to their parent element
that they don't appear anywhere else. For example, <stop>
is only found within a <radialGradient> or <linearGradient>.
So, there isn't any reason to define a content set for
Stop elements.

Hope this helps,

Dean
