[6] [DFN[[[HTML 5.1]]]] は、 [[W3C]] [[HTML WG]] による [[HTML]] の仕様書です。
[[WHATWG]] の [[HTML Standard]] をベースに独自の編集を加えており、互換性はありません。
[[HTML WG]] は [[HTML5]] (5.0) を「[[安定版]]」、 [[HTML 5.1]] を「[[開発版]]」と位置付けています。
[10] なお、 [[WHATWG]] の [[Ian Hickson]] は、 [[W3C]] の行為は[[剽窃]]であると厳しく非難しています

* 開発
[51] [[W3C]] [[HTML WG]] が開発を開始しましたが、解散しました。
現在は [[WPWG]] が引き継いでいます。
[53] 編集体制は二転三転しており、時期により異なります。
* 歴史
** HTML.next
[11] [DFN[[[HTML.next]]]] は、 [[W3C]] における [[HTML5]] の次期版を表す用語です。
[12] 2010年頃から [[W3C]] [[HTML WG]] や [[WHATWG]] の周辺で使われるようになり、
2011年には [[HTML WG]] では一般的に使われるようになりました。
[[WHATWG]] はバージョン番号のない [[HTML Living Standard]] に移行しているため、
専ら [[W3C]] でのみ使われるようになっています。

[5] [[HTML 5.1]] は [[WHATWG]] の [[HTML Standard]] から [[HTML WG]] の好まない部分を省いたものですが、
編集が雑なので虫食い状に [[WHATWG]] の規定が残っていて、低品質です。
例えば [CODE(HTMLa)@en[[[itemref]]]] [[属性]]は [[HTML 5.1]] に含まれていないはずですが、
[[IDL]] や索引には載っています。 [CODE(HTMLe)@en[[[hgroup]]]] [[要素]]は [[HTML 5.1]]
では廃止されているはずですが、[[HTML構文]]におけるタグの省略に関する規定で出てきます
(この部分は本来不適合な[[要素]]について言及していません)。
[CODE(DOMa)@en[[[complete]]]] [[属性]]の定義では [[HTML 5.1]] に含まれない
[CODE(HTMLa)@en[[[srcset]]]] [[属性]]が参照されています。

> A year ago, there was a lot of discussion about modularising HTML and the

> that Robin Berjon worked on '''['''7''']'''. The feedback we have received on the
> proposed split by chapter is that it doesn't provide the benefits that
> modularisation promises. To do this properly will require refactoring of the
> specification. We would still like to do this, but we recognise it is a lot
> of work and there are drawbacks as well as benefits.
> One approach to test modularisation is to encourage people working on a
> specific section to split it out from the "main" HTML specification, move it
> independently to Recommendation, so that it can be referenced normatively
> from the base specification. This way we can get some experience of the
> process without undertaking a massive project before we really know the
> costs and benefits.

> Finally, a lot of time last year was spent talking about modularisation of HTML. But that is much more than just breaking the spec into pieces – it requires a lot of deep refactoring work to provide any benefit. We want to start building new things that way, but we are mostly focused on improving quality for now.
> So we have taken some time to get going, but we’re now confident that we are on track to deliver a Recommendation for HTML 5.1 this year, with a working approach that will make it possible to deliver a further improved HTML Recommendation (5.2? We’re not too worried about numbering yet…) in another year or so.
