I think high|low|medium should me more meaningful or in other words self-explaining. What about "newFeature", "incompatibleChange", "minorChange"?
Well if the output of that is going to be just more visibility to some actions, then this will increase complexity adding poor value.
The idea (at least the one in my head) is that in your can sort/select actions base on the "importance" (or impact... or gavity). So you can create a status just only for important actions.
Given that, why do not use the already priority attribue that has been used on <actions>, but instead of the actions elements, move it to the child element <action>?
