** 特定の MIME 型に関するもの
- [25] [[RFC 4627]] : [[JSON]] の [[charset]] [[sniffing]] について言及しています
* RDFa 処理器の Sniffing
[50] [[RDFa 1.1]] に基づく [[RDFa処理器]]は、 [[MIME型]]によって[[ホスト言語]]を決定しなければ[['''なりません''']]。
[[MIME型]]を決定できないか未対応の時は、 [CODE(MIME)@en[[[application/xml]]]] としなければ[['''なりません''']]。
[SRC[>>49]]
[51] >>50 の直後にこれと矛盾する次のような「NOTE」があります。 [[MIME型]]が無い時、
[[DOCTYPE]]、[[根要素]]、[[拡張子]]、[[利用者]]定義の引数など追加の仕組みを用いても[['''構いません''']] [SRC[>>49]]。

> One browser started ignoring CSS files in one very specific
case, namely only if the document had a DOCTYPE that, at the time, was
basically unused. (I was one of the two people pushing for this.) It broke
some sites, but comparatively few in the grand scheme of things. (Though
we still get bug reports about this today, so maybe it wasn't that good an
idea after all.)
