Why using text/html for XHTML is bad

[shaun]

What usually happens to authors who decide to send XHTML as text/html
is the following:

1. Authors write XHTML that makes assumptions that are only valid for
tag soup or HTML4 browsers, and not XHTML browsers, and send it as
text/html. (The common assumptions are listed below.)

2. Authors find everything works fine.

3. Time passes.

4. Author decides to send the same content as application/xhtml+xml,
because it is, after all, XHTML.

5. Author finds site breaks horribly. (See below for a list of
reasons why.)

6. Author blames XHTML.

Steps 1 to 5 have been seen by every single person I have spoken to
who has switched to using the XHTML MIME type. The only reason step 6
didn't happen in those cases is that they were advanced authors who
understood how to fix their content.cheers guys
