The following errata report has been submitted for RFC9559,
"Matroska Media Container Format Specification".

--------------------------------------
You may review the report below and at:
https://www.rfc-editor.org/errata/eid8615

--------------------------------------
Type: Technical
Reported by: Steve Lhomme <slhomme@matroska.org>

Section: 5.1.4.1.24

Original Text
-------------
   path:  \Segment\Tracks\TrackEntry\AttachmentLink
   maxOccurs:  1
   maxver:  3

Corrected Text
--------------
   path:  \Segment\Tracks\TrackEntry\AttachmentLink
   maxver:  3

Notes
-----
The "maxOccurs" set to 1 is bogus. There can more more than one AttachmentLink in a TrackEntry. It should be removed to allow any number of AttachmentLink per TrackEntry.

This corresponds to this fix: https://github.com/ietf-wg-cellar/matroska-specification/pull/932

Instructions:
-------------
This erratum is currently posted as "Reported". (If it is spam, it 
will be removed shortly by the RFC Production Center.) Please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party  
will log in to change the status and edit the report, if necessary.
