我正在处理一个文档，该文档在正文和脚注中都包含索引项。脚注项的显示方式与文本项不同。为了实现这一点，我遵循了这答案，我将使用相同的 mwe 来说明我的页码顺序问题。我想要的结果是：
索引，1，1n1，2n2，3，3n3，5ff。
我尝试过两种方法：
1.
对于索引，我定义了一个标记范围 (f., ff.)，它工作正常。问题在于位置类别顺序；位置类别相互跟随，这意味着，首先是文本中的所有项目页码 (\index)，然后是脚注中的所有项目页码 (\indexfn)。是否有可能构建“混合”位置类别顺序？

;; End
如果我添加“-M ff-ranges”，我会得到正确的顺序，但没有 f.、ff。（我相信原因与下面描述的相同）
2.
我只在所有地方使用 \indexfn，这是可能的，因为它可以识别它是否在脚注中。顺序是正确的。这里的问题是我不知道如何为 var-location-class 定义 markup-range。文档说：
... 目前仅允许在标准类中构建范围
:var，且:min-range-length不能一起使用。
还有其他我没看到的可能性吗？
