I'm afraid that with the pdfx example that I put in the first post I
have caused a little confusion. pdfx is not part of my workflow. I only
used it once a long time ago. I've cited the code from that package here
as another example of arbitrary code that can be placed before
\documentclass. As I said, there are many more examples and possible
cases: \DocumentMetadata and \PassOptionsToPackage are two typical
cases. But, as I have already mentioned, /almost/ any LaTeX code can be
accommodated before class declaration. Even simple comments. Why not
think about a hypothetical case in which a user needs to create from Org
a *.tex file that contains comments before \documentclass? With a
LaTeX_pre_header keyword that would be possible.
