palemieux has just created a new issue for https://github.com/w3c/imsc:

== Incompatible SMPTE ST 2052-1:2013 extension namespace name ==
[SMPTE ST 2052-1:2013 (SMPTE-TT)](https://www.smpte.org/sites/default/files/ST2052-1-2013.pdf) modified the extension namespace name originally defined in SMPTE ST 2052-1:2010, from `http://www.smpte-ra.org/schemas/2052-1/2010/smpte-tt` to `http://www.smpte-ra.org/schemas/2052-1/2013/smpte-tt`. [ed.: It is not clear why this change was made.]

IMSC 1.0.1 and IMSC 1.1 use `http://www.smpte-ra.org/schemas/2052-1/2010/smpte-tt` exclusively for the `smpte:backgroundImage` attribute.

IMSC 1.0.1 references undated SMPTE ST 2052-1.

IMSC 1.1 references SMPTE ST 2052-1:2013.
