Hi Futomi san,

I understood your intention. On the other hand, I cannot have conviction that the consensus of this 
BG member accords with it.

Do we only define the requirements of web based signage as libraries or frameworks for common 
browsers (HTML5 in wide sense)?

Or do we put the dedicated native signage player based on these requirements not to be based on 
common browsers in our scope? There are many native code "player" in the world.

It will be considered that it is a profile of the subsets of HTML5 in wide sense if expectation to 
the latter is included.

I think that this is one of a important point. And I think that we should specify it in this 
document by the situation of consensus.

Regards,

Satoru
