Focus topic for this week

Issue-239 3D and images<https://github.com/w3c/ttml2/issues/239>
Can we resolve this on the call?

Inclusion of foreign namespace elements – is it only permitted on metadata elements, or anywhere? Do we need additional conformance language? See also IMSC issue foreign namespace usage is underspecified<https://github.com/w3c/imsc/issues/213>
