metadata in the VTT file header

Hi

we've mentioned this in passing, and maybe we need an issue or a bug tracker for this.  

We probably need to put in the file header some meta-data, that could be used for (for example)
* if the VTT file is used by a 'media player' outside a web context
* when the file is going to be, but not yet, embedded in a web context, information that will be needed to do that embedding right

These categories probably overlap.  I'm thinking of examples like
-- "looks better if these style-sheets are used" 
-- "has an overall language of en-US"
-- "is intended for this 'kind' in HTML"
-- "when used with the expected mpeg-2 transport stream, <this> VTT timestamp is (maps to) <that> MPEG-2 clock reference"

and so on.

Do we have proposals, or are we at the use-case and data-collection stage?
