Features

• A new PPX has been added that allows to use tyxml with the HTML/SVG syntax, using the markup library (contribution by Anton 'aantron' Bachin).

Renaming and deprecations

• Files in the tyxml library are now packed in a Tyxml module. If you were using one of Html5, Svg and Xml module, simply open Tyxml.
• All Html5 modules are now named Html
• Various attributes and elements have been renamed. The original versions have been kept and marked deprecated.
• Various elements that were both deprecated in the HTML specification and not usable due to typing constraints have been removed.
