The following errata report has been held for document update 
for RFC7541, "HPACK: Header Compression for HTTP/2". 

You may review the report below and at:

Status: Held for Document Update
Type: Editorial

Reported by: Christian Parpart <trapni@gmail.com>
Date Reported: 2015-12-31
Held by: Barry Leiba (IESG)

Section: Appendix A.

Original Text
   Table 1 lists the predefined header fields that make up the static
   table and gives the index of each entry.

Corrected Text
   Table 1 lists the predefined header fields that make up the static
   table and gives the index of each entry.

   This list of predefined header fields is NOT sorted.

The list of header fields actually is sorted except for one field. The field with index 19 should be between the fields with index 14 and 15).

That is why it gives the false impression that an implementer may use binary search algorithm to look up for header fields (while encoding) in order to retrieve their index numbers.

I highly encourage to at either move that field up or at least clarify that this list (even though it looks sorted), it is not.
