Remember a couple of years ago, when serving XHTML with a
text/html MIME type was the worst you could do if you were serious about your trade?
But what happened then? People seemed to stop caring, and in this current day, no one seems to write about it. Also, the web is full of so many web sites with XHTML served as
text/html instead of the proper
application/xhtml+xml that it feels like not even a googol can describe it.
When did people stop taking this into account? Why isn’t anyone pointing this out to unaware colleagues anymore?
