Re: [SRI] format of the integrity attribute

I support getting rid of the ugly ni:/// syntax. You can't re-use the TYPE
attribute like that, though. In HTML the type attribute means "treat this
as if it were..." and in SRI we're saying "Fail if it's not ...".

splitting the hash from the required-type info has other advantages than
syntax: for instance the spec says to use the "strongest" hash, but what if
there are two that are the same hash algorithm but with different ?ct
values? +1 to splitting the two, but we'll have to use a new type attribute
like the "integritytype" that I think Martin suggested, or maybe
"required-type".
