You are doing nothing terribly wrong. :)
What is happening is:
* you are using XHTML Basic 1.1, which the validator does not have (yet) in its
internal catalog.
* because the document type is unknown to the validator, it looks at other
information, and finds that your document is served as text/html. hence "OK, it
must be some kind of classic HTML".
* the validator parses your XHTML as classic HTML and gets all confused by all
this apparent XML stuff in a document that supposedly isn't.

Morality: you should have served your XHTML content as application/xhtml+xml.
Serving it as text/html is tolerable for XHTML 1.0 authored according to
http://www.w3.org/TR/xhtml1/#guidelines but for XHTML Basic 1.1 it's really not
recommended.

In any case, many thanks for your report. I'm going to add XHTML Basic 1.1 as a
known document type and everything should be working soon.

Thank you,
olivier
