Andrea, thank you. Even if the html version does not reflect a difference, your work is an improvement because it will have less errors output during pdf to html. I have checked into GIT already, your Advanced.tex changes because I needed to check in changes to Installation.tex for the location of the new build package farm area by Andrey and update Elive for Bookworm, Debian 12 and I did not want them to get lost. I am in the process of being a second pair of eyes for the other 12 files you modified. ...Phyllis
