Description

This listing provides all obsolete elements along with obsolete attributes per element: https://www.tutorialrepublic.com/html-reference/html5-tags.php.

We will remove attribute definitions in Sink and Parser (XHTML5 and derived like Xdoc and FML). Moreover these changes will break some usage:

• Aligning of table cell must now happen through CSS on the TDs rather than providing it to table rows. There is no simple way to parse and write it in a format-neutral manner w/o huge effort.
• Replace name with id on anchors.
• Table borders must be solved by CSS now
• Affected elements: img, hr, links (a), table, td/th, sections, verbatims, tr

Virtual all deprecated attributes have been superseded by CSS. Improve also tests because code is stricter now.
