解説

choice要素の子要素は全て、同じ部分の異なる選択肢を示しているので、それらは択一的であるとするのが自然である。 けれども、テキストを完全に表現するには複数の選択肢を並列的に扱う必要がある場合もあるだろう。

choice要素は、自らを入れ子にできることにも注意して欲しい。

符号化時にありうる選択肢ではなく、1つの作品にある複数の本文を記録する目的では、 13.1 The Apparatus Entry, Readings, and Witnessesで扱われているapp要素などが望ましい。
例

An American encoding of Gulliver's Travels which retains the British spelling but also provides a version regularized to American spelling might be encoded as follows.

articles, the said man-mountain shall have a daily allowance of
meat and drink sufficient for the support of <choice>
