[xwiki-devs] [Proposal] Modify "xhtml/1.0" renderer to generate valid XHTML and introduce a new "xhtmlfragment/1.0" renderer

Hi devs, One issue we have ATM is that the xhtml/1.0 parser requires valid XHTML but the xhtml/1.0 renderer generates invalid XHTML (it generates fragments only). This causes https://jira.xwiki.org/browse/XWIKI-13278 for example. I’m proposing to: * Modify "xhtml/1.0" renderer to generate valid XHTML (i.e. xml declaration + doctype + html element) * Introduce a new "xhtmlfragment/1.0” renderer * Have annotated versions of both for the WYSIWYG editor WDYT? Thanks -Vincent
