对于这类事情，Context/luatex 比 Latex 有更好的支持：使用 Context 的图层对交互式文档有一些支持，当在 PDF 中单击按钮时，图层的内容会发生变化。我认为这必须使用标签来完成。
我从未听说过诸如嵌入表单、数字签名或在生成的 PDF 中嵌入 Latex/Tex/Context 源之类的东西，但原则上这都是可能的。
Hmm, well, yes, sort of.
There isn't really sophisticated support for tagging, and what there is, is implemented in pdftex/luatex. Support for bookmarks and in-document cross-references is done using tagging. There's also been some more sophisticated work shown at TUG conferences, but this is all in the pipeline for now.
Context/luatex has better support that Latex for this sort of thing: there's some support for interactive documents using Context's layers, where the contents of the layers change when buttons are clicked in the PDF. I think this must be done using tagging.
I've never heard of anything like embedded forms, digital signing, or embedding the Latex/Tex/Context source in the resulting PDF, but in principle this is all possible.

嗯，嗯，是的，有点。
对于标记并没有真正复杂的支持，而有的支持是在 pdftex/luatex 中实现的。对书签和文档内交叉引用的支持是使用标记完成的。 TUG 会议上还展示了一些更复杂的工作，但这一切目前都在酝酿之中。

我对 pdfLatex 一般有同样的问题，发现了这个：

但到目前为止我还没有测试它。
I've the same question with pdfLatex in general and found this:

But I don't test it till now.
