The current draft (-02) says, "The endpoint establishing a new stream
can assign a priority for the stream."
However, the spec does not define how a stream established using
PUSH_PROMISE can assign the priority for a stream, nor does the spec
discuss whether the notion of stream priority applies to push streams.
The spec currently states that PUSH_PROMISE is followed later on by a
HEADERS frame.
If priority applies to push streams, then we need to add that priority
can be assigned by allowing the use of a HEADERS+PRIORITY frame.
Otherwise, we need to clarify the spec text to say that push streams
have no priority.
