[whatwg] [WA1] Insignificant white space

[fantasai]

# The whitespace characters U+0020 SPACE, U+000A LINE FEED, and U+000D CARRIAGE 
# RETURN are always allowed between elements.

What about U+0009 TAB?

# must have the content attribute set to the literal value 'text/html; charset='
# immediately followed by the character encoding

If I understand correctly, HTTP headers aren't quite so particular about
whitespace. Do you intend to require that exact sequence of characters,
or would, for example, removing the space after the semicolon or using
three spaces there also be acceptable?
