[Ocamlnet-devel] attributes without values

[Ashish A. <aga...@gm...>]

Html like "<div data-id></div>" gets parsed as:

Nethtml.Element ("div", [("data-id", "data-id")], [])

The value is set to the attribute name, which seems wrong. The correct
solution would be to change the type of an element so that values are
`string option`, but I'm guessing that's infeasible. Alternatively, the
parser should set the value to the empty string.
