  I still suspect Bart's publisher means the tags that are part of
Tagged PDF, even if he doesn't know their actual name, and has clearly
a wrong idea of what they really contain.

  The bad news is, TeX's support for Tagged PDF is very weak.  There
have been some experiments by Han The Thanh recently, but no general
progress that I am aware of.  In any case, generating fully tagged PDF
would need a lot of collaboration between the engine and the macro
package.

  A bit, but the guy also asks for "header information", which sounds
more like the kind of information you put between PDF's BDC / EMC
operators.
