Precedence: list

The following errata report has been submitted for RFC7959,
"Block-Wise Transfers in the Constrained Application Protocol (CoAP)".

--------------------------------------
You may review the report below and at:
https://www.rfc-editor.org/errata/eid7523

--------------------------------------
Type: Editorial
Reported by: Christian Amsüss <christian@amsuess.com>

Section: 3

Original Text
-------------
   then the block number (NUM), more bit (M), and block size exponent
   (2**(SZX+4)) separated by slashes.  For example, a Block2 Option

Corrected Text
--------------
   then the block number (NUM), more bit (M), and block size
   (2**(SZX+4)) separated by slashes.  For example, a Block2 Option

Notes
-----
The examples are given in the style of "2:1/1/128", wher 128 is the size (2**(SZX+4)), not the size exponent -- it contains the size exponent in the expression, but the full expression is the size.

(Reporting this as an erratum because the use of "SZX" for "size" instead of "size exponent" has some potential for spreading and creating confusion; for example in Wireshark at https://gitlab.com/wireshark/wireshark/-/merge_requests/10763)

Instructions:
-------------
This erratum is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party
