（这个问题接着如何使用 xetex 模拟 \pdfstartlink 和 \pdfendlink？）
笔记：我用了最后一个TikZ/PGF 的 CVS 版本。
使用xelatex，我想在 tikz 节点中创建注释。以下 MWE 显示了我的问题：第二个开关（通过 TikZ）很糟糕。
\documentclass{article}
\usepackage{ocg-p}
\usepackage{tikz}
\def\mypdfstartlink#1{%
\special{pdf:bann << /Subtype /Link /Border [1 1 1] /A << #1 >> >>}%
}
\def\mypdfendlink{%
\special{pdf:eann}%
}
\long\def\switchocg#1#2{%
\leavevmode%
\mypdfstartlink{ /S/SetOCGState /State %
[/Toggle \csname OCGpdfobj#1\endcsname\space] }%
#2%
\mypdfendlink%
}
\begin{document}
\begin{ocg}{ocg 1}{ocg1}{1}
Some text...
\end{ocg}
\switchocg{ocg1}{text switch}
\tikz\node{\switchocg{ocg1}{tikz switch}};
\end{document}
