Frameworks and libraries that generate html should output well-formed html
that can be used for both HTML serialization (text/html) and XML
serialization (application/xhtml+xml). This implies that Django should
continue to output XML compatible markup even for HTML5.
This do not mean that Django need to be restricted by the XHTML-
Transitional and XHTML-Strict standard. It only means that HTML5 needs to
be written in a XML compatible style.
This affects Django in three ways:
1. HTML must be well-formed. All start-tags needs an end-tag (except self-
closing tags). This is already the case.
1. All self-closing tags must end with '/>'.
2. All boolean attributes must have a value e.g 'checked="checked"'.
I will say that this time is the best time ever to serve pages with
application/xhtml+xml, because all browsers supports it. IE was the road
blocker for year, but since IE9 it supports it as well. Se a list of the
[https://developer.mozilla.org/en-
US/docs/Web/HTTP/Content_negotiation/List_of_default_Accept_values default
value of the Accept header] for various browsers from Mozilla.
