commit fd378450755b698cc3ddb1a8d14e8b78d19c57a2
Author: Thibaut Cuvelier <[email protected]>
Date: Thu Mar 21 21:32:45 2024 +0100
Amend 16660d12.
The previous commit introduced wrong behaviours for <>. The new code
carefully escapes what needs to be escaped from LaTeX, using the now-standard
XML tools (XMLStream).
