[10] [DFN[[[XInclude]]]] は、 [[XML文書]]に他の[[XML文書]]を[RUBYB[取り込んで]@en[include]]
(論理的な) [[文書]]の一部を構成させるための [[XML]] の[[語彙]]です。

[11] 多くの[[マーク付け言語]]で共通して使われ得る「取り込み」の記述方法と処理を共通化することを狙っていましたが、
標準化が遅れたこと、各言語それぞれの事情を考慮する方法がないことなどからごく一部でしか採用されませんでした。

[12] 小改訂の [DFN[[[XInclude 1.1]]]] の開発も (相当の低速度で) 進められていましたが、
[[XML]] 全体の衰退が進む中で完成しても一体どれだけ使われるかは謎でした。
結局 [[XML Core WG]] の閉鎖に伴い2016年に開発中止されました。

[CODE(XMLa)@en[[[xml:id]]]] や [[XLink]] が同様に[[マーク付け言語]]共通の[[語彙]]となることを狙っていましたが、
いずれも成功していません。
