Thanks Martin for opening the issue of #336.

Thanks Tatsuhiro, I missed that discussion.

But I think that using a smaller header table with a indexing representation in
encoding causes a problem even if the static table is not referred.

It is because eviction at the smaller side leads inconsistency of reference
  sets between encoder and decoder and differenet header sets are emitted.
That's why I wrote a withoutindexing representation.

Did I miss something?

I think the latter is not so complex. Just the order of processing
need to be defined to avoid confusion.
