I was reading this blog by James Bennett regarding HTML vs XHTML . He writes :
I don’t have any need for namespaced content; I’m not displaying any
complex mathematical notation here and don’t plan to, and I don’t use
SVG for any images. So that’s one advantage of XHTML out the window. I
also don’t have any need for XML tools; all the processing I need to
do can be handled by HTML-parsing libraries like BeautifulSoup. That’s
the other advantage gone.
What does he mean by namespaced content and what advantage does it provide us ?

XML namespaces allow including XML elements defined in a schema other than that of the main document. Specifically, the article talks about MathML and SVG, which are XML-based formats that can be directly embedded in an XHTML document using namespaces, looking like this:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:m="http://www.w3.org/1998/Math/MathML">
XHTML content goes here
<m:math>
MathML content goes here
</m:math>
more XHTML content
</html>
