Section 4.2.5 says:

The primary media type typically carried within the Multimedia
Streaming service class is video; as such, it is RECOMMENDED to map
this class into the Video Access Category (AC_VI), which it will by
default (as described in Section 2.3).  Specifically, it is
RECOMMENDED to map AF31, AF32, and AF33 to UP 4, thereby admitting
Multimedia Streaming into the Video Access Category (AC_VI).

It should say:

The primary media type typically carried within the Multimedia
Streaming service class is video; as such, it is RECOMMENDED to map
this class into the Video Access Category (AC_VI);
however, by default (as described in Section 2.3), this
service class will map to UP 3 and, thus, the Best Effort Access
Category (AC_BE).  Therefore, a non-default mapping is RECOMMENDED,
such that AF31, AF32, and AF33 map to UP 4, thereby admitting
Multimedia Streaming into the Video Access Category (AC_VI).

Notes:

This correction addresses an inconsistent mapping in Section 2.3, specifically:
"Multimedia Streaming (AF3-011xx0) will be mapped to UP 3 (011) and treated in the Best Effort Access Category (AC_BE) rather than the Video Access Category (AC_VI), for which it is intended". It does not seek to endorse or change any mappings.
