pdfx我正在尝试使用 XeTex 并利用该包创建 PDF/A 文件。pdfx 文档第 96 页似乎表明应该适应XeTex。
我也尝试过xmpincl明确使用（它通常由继承pdfx），但显然仅适用于 pdflatex
如果我注释掉，\usepackage[a-1b]{pdfx}那么我会得到我期望的元数据，但我的输出不符合 PDF/A。
顺便说一句，我正在使用 xelatex 来嵌入字体；这是 PDF/A 的要求……在 pdflatex 中这样做真的很痛苦。
关于如何在 PDF 中获取元数据有什么想法？
\documentclass{book}
\usepackage[a-1b]{pdfx}
\usepackage{hyperref}
\hypersetup{
pdftitle={This is the title},
pdfauthor={This is the author},
pdfcreator={This is the creator}}
\usepackage[main=english]{babel}
\begin{document}
This is some text
\end{document}
另外，以下是xetex --version
