Write a section with LaTeX suggestions

[matteosecli]

Just a reminder for myself.

Some nice things to write about:

• pdfx: https://ctan.org/pkg/pdfx and https://github.com/serviceprototypinglab/latex-pdfa
• pdfathesis: https://www.mun.ca/math/graduate/grad-thesis/
• Warning about zero-width glyphs or non-matching widths: https://tug.org/pracjourn/2010-1/beccari/beccari.pdf
• General suggestions (see also http://support.river-valley.com/wiki/index.php?title=Generating_PDF/A_compliant_PDFs_from_pdftex)

This is a totally different way to create pdf/a but for people coming to this repo, it may be worth it to check out the hyperxmp package for pdflatex.
https://ctan.org/pkg/hyperxmp

For me it created pdf/a from some documents without breaking anything.

usage is pretty simple: Just add \usepackage{hyperxmp} anywhere before including hyperref.
