RE: A11Y-ACTION-312: Review bug 27054 and check it's ok

Text has been added to the EME specification. The changes have been tracked on Github [1].

Section 8.4 Supported media was added [2]. Of particular relevance is section 8.4.3 Unencrypted in-band support, which contains the following text [3]:

"In-band support content, such as captions, described audio, and transcripts, should not be encrypted.

NOTE
Decryption of such tracks - especially such that they can be provided back the user agent - is not generally supported by implementations. Thus, encrypting such tracks would prevent them from being widely available for use with accessibility features in user agent implementations.

Implementations that choose to support encrypted support content must provide the decrypted data to the user agent to be processed in the same way as equivalent unencrypted timed text tracks."

This would seem to resolve bug 27054 [4]. Suggest it can be closed.
