[i18n-activity] Can <named-item> altText have xml:lang?

aphillips has just created a new issue for 
https://github.com/w3c/i18n-activity:

== Can <named-item> altText have xml:lang? ==
https://w3c.github.io/ttml2/spec/ttml2.html#metadata-value-named-item

The `<named-item>` construct has an attribute `altText` intended to 
provide descriptive text primarily for images (similar to `alt` in 
HTML). There is no associated language metadata. Should there be?
