Could you give an example of how? I don't understand how it would work if
we re-use an an existing MIME type. If you have any concrete examples I
could look at that would be ideal.

More flexible and expressive than what?

How would this manifest itself in this context? Are you suggesting that we
should change the microdata to JSON serialisation rules somehow?

Could you give an example of how this would help an application?
It would help if you described what precise changes you would like to see
to the algorithms, so that I better understood the implications here.

I don't understand what this means.

Currently, the data is just stored as JSON, it's not a new format. It's
only a new MIME type to allow easier filtering in the drag-and-drop API.
