            Bug ID: 23558
           Summary: Requirement to ignore additional top-level boxes in
                    ISO BMFF limits forward compatibility.
           Product: HTML WG
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: minor
          Priority: P2
         Component: Media Source Extensions

Section 12.2.2 states "Valid top-level boxes defined in ISO/IEC 14496-12 other
than moov, moof, and mdat are allowed to appear between the end of an
initialization segment or media segment and before the beginning of a new media
segment. These boxes must be accepted and ignored by the user agent and are not
considered part of the media segment in this specification."

This requires such additional boxes to be ignored, wheras it would be better if
it was simply allowed to ignore them.

Replace: "These boxes must be accepted and ignored by the user agent and are
not considered part of the media segment in this specification."

With: "These boxes must be accepted and may be ignored by the user agent and
are not considered part of the media segment in this specification."
