My point is that CONTINUATION frames may depend on the compression state, for example by using a reference to an entry of the dynamic header table for the header name. This dependency enforce an order between CONTINUATION frames and HEADER frames from other streams.

I see two possibilities for removing this dependency:
- Allow only literal header representations, not indexed, and using a literal for the header name.
- Use a specific compression state for the CONTINUATION frames where the header table size is 0: this would allow referencing entries of the static table (either as a whole, or only for the header name).
