strict tagging mode that raises errors

[teepeemm]

I would like to request a strict mode that would raise errors for otherwise valid LaTeX that fails the specified pdfstandard. For example:

• omitting a \title
• creating a table without setting header-rows or header-columns
• using \includegraphics, {tikzpicture}, \tikz, or {picture} (others?) without setting alt, artifact, or actualtext. (Currently, \includegraphics issues a warning in this case.)
• I'm sure there are other possibilities

The syntax could be \tagpdfsetup{strict-tagging} so that we could allow \tagpdfsetup{strict-tagging=false} and grouping.
