That language applies only to SVG-static, SVG-animated, and SVG-all.
Even if it applied to all feature strings, it's not clear what "all
of the corresponding language features" refers to.

The PaintAttribute feature string does not correspond to "the viewer
can paint shapes" but "the viewer supports the Paint Attribute Module".
The draft does not say anywhere whether an implementation can support
Shape even though it fills all shapes with black, for example.
