[whatwg] Handling of uplicate attribute names in tokenisation stage

[Thomas Broyer]

http://www.whatwg.org/specs/web-apps/current-work/#attribute1
"""
if there is already an attribute on the token with the exact same
name, then this is a parse error and it must be dropped, along with
the value that gets associated with it (if any).
"""

I assume the "it" in "it must be dropped" refers to the attribute
being currently parsed, not the one which were already there on the
token (at least, this is what was assumed in python's html5lib), but
it's not clear IMO.

Or is it just my English?
