推荐答案

它们完全无关.

Choice 表示在元素的内容模型中，您可以使用多个子元素之一:例如，在文档中，您可以选择章节或附录作为子元素.

Choice indicates that within the content model of an element, you can use one of several child elements: for example within a document you have a choice of chapter or appendix as child elements.

枚举用于限制可以出现在文本或属性节点中的值，例如表示颜色属性的值必须是红色、绿色或蓝色.

Enumeration is used to restrict the values that can appear in a text or attribute node, for example to say that the value of a color attribute must be red, green, or blue.
