考虑以下一段代码：
\documentclass{book}
\usepackage{cleveref}
\usepackage{lipsum}
\begin{document}
\chapter{Chapter One}
\section{Section One.One}
\label{mysection}
\lipsum
\section{Section One.Two}
Please ignore \cref{mysection}.
\chapter{Chapter Two}
\section{Section Two.One}
As you may have noticed, \cref{mysection} is useless.
\end{document}
默认情况下，两种用法\cref均能获得Section 1.1预期的效果。
是否可以改变参考文献的显示方式，以便第二使用\cref上述方法将打印Section 1 of Chapter 1？即，也命名父计数器。
然而，这只能外部\cref自己的章节，因此上例中第一次使用时应该打印Section 1。
这来自规范文本的用例，其中文档分为“文章”和“逗号”，并且最好有“文章 2 的逗号 1”或“文章 2，逗号 1”之类的引用。

确定一个计数器的父计数器很容易，如果只有一个父计数器，那么这是一个唯一的映射。
我按顺序存储了文档开头定义的所有计数器，并“破解”了列表\cl@X（X作为驱动程序计数器名称，例如chapter），将其内容存储到包含父计数器的属性列表中。
该\getparentcounter宏可用于检索该值。
现在zref包存储了属性childcountervalue，parentcountervalue以便parentcountername稍后使用 检索它们\zref@extract。
锚点也被存储起来，以备我们使用hyperref。
宏\parentcref和\parentCref将输出父计数器和子计数器，其中第一个字符为小写（实际上是计数器名称），第一个字符为大写，即section → Section等等。
代码假设计数器仅使用数字，即\arabic{foo}。我将尝试消除此限制。

看对章节逐个部分进行重新编号，在章节编号的交叉引用中添加部分编号作为后缀对于类似的问题，但这不是重复的！
