Description
In TTML2's <data> element, an encoding can be specified, being one of:
- base16
- base32
- base32hex
- base64
- base64url
Do we need to require processor support for all of them, or will the default base64 be adequate?
Also, it is possible to specify a length attribute that provides some feasibility of error checking, since the decoded data must be the specified length in bytes. Is requiring support for this a net benefit? Would it be used?
