使用 xelatex 和 pdfx 添加 xmp 元数据时出错

Question 1

您正在混合xmpincl和pdfx期望如何找到和创建 XMP 文件。该命令\includexmp来自xmpincl，并且pdfx不想与它有任何关系。pdfx提供了一个简化的界面，但它有严格的要求：

您的.xmpdata文件必须与主文件同名.tex（如果使用filecontents包，则用作\jobname.xmpdata文件名）；
您实际上并没有加载该.xmpdata文件，这意味着它必须与主文件位于同一目录中.tex；并且
您不需要xmpincl明确加载，并且这样做也不会获得任何好处。

如果我遵循这些指示，您的示例文件对我来说就有用。

编辑好的，上面的文件可能不是非常小，但对我来说仍然有效。为方便起见，我在下面发布了我使用的确切文件，其中包括命令，\listfiles以便我们可以比较文件版本。从您提供的错误消息来看，我认为您可能拥有该文件的过时版本（可能是 1.3 版？）

运行pdflatex该文件会给我这个文件列表（顺便说一句，这也是 MWE 的另一个原因：减少问题和答案中多余的膨胀）：

因此，我的pdfx是 2016 年的 1.5.6 版本。CTAN 上的先前版本看起来它是 2008 年的 1.3 版。
