[5] [[W3C]] [DFN[[[XML Core WG]]]] は、[[XML]] および関連仕様をメンテナンスしている[[作業部会]]でした。

[6] 完成済みの仕様書のメンテナンスのみでモチベーションが低いのか作業の進捗は大変遅く、
議論が始まってから仕様書が改訂されるまで数年レベルの時間がかかるのが普通になっています。

[15] 2016年夏、主要参加者の1人である [[Norman Walsh]] が多忙を理由に離脱を表明した [SRC[>>13]]
のを契機 [SRC[>>12]] に閉鎖されました [SRC[>>16]]。

;; [18] [[XML Core WG]] で開発されたものもあれば、他の [[WG]]
が閉鎖されて移管されたもののほとんど放置状態のものもあります。

* 歴史

;; [19] [[XML]] の歴史の項も参照。

[20] 
[[XML]] や周辺の各種仕様が、担当 [[WG]] が閉鎖されるたびに移管されて
[[XML Core WG]] でメンテナンスが継続されていました。

[21] 
しかし専門グループが閉鎖されるほどですから、
あまり関心も高くなく、担当編集者以外ほとんど何もせず、
担当編集者もたまにしか仕事をしないという有様でした。
一世を風靡した [[XML]] の凋落ぶりを絵にしたような [[WG]] でした。
