strange behaviour from css validation

Hi:

I just tried to CSS validate a page using

http://jigsaw.w3.org/css-validator/validator?uri=http%3A%2F%2Fwww%2Ddb%2Eresearch%2Ebell%2Dlabs%2Ecom%2Fuser%2Fpfps%2Fdaml%2Fdaml%2Boil%2Daxioms%2Ehtml

and got

CSS
                                                 Validator
                                                         Error

Target:
http://www-db.research.bell-labs.com/user/pfps/daml/daml+oil-axioms.html

Please, validate your XML document first!

Line 280

Column 7

An invalid XML character (Unicode: 0xa0) was found in the element
content of
the document.


but I just did that, getting

Below are the results of checking this document for XML well-formedness
and validity.

    No errors found! *

            Congratulations, this document validates as XHTML 1.0
Transitional!

To show your readers that you have taken the care to create an
interoperable Web page, you may display this icon on any page that
validates. Here is the
HTML you could use to add this icon to your Web page:

  <p>
    <a href="http://validator.w3.org/check/referer"><img
        src="http://www.w3.org/Icons/valid-xhtml10"
        alt="Valid XHTML 1.0!" height="31" width="88" /></a>
  </p>

If you like, you can download a copy of this image (in PNG or GIF
format) to keep in your local web directory, and change the HTML
fragment above to
reference your local image rather than the one on this server.

If you use CSS in your document, you should also check it for validity
using the W3C CSS Validation Service.

If you would like to create a link to this page (i.e., this validation
result) to make it easier to re-validate this page in the future or to
allow others to validate your
page, the URI is:


http://validator.w3.org/check?uri=http://www-db.research.bell-labs.com/user/pfps/daml/daml+oil-axioms.html

(Or, you can just add the current page to your bookmarks or hotlist.)

Caveat

This validator is based on SP, which has some limitations in its support
for XML.

What gives?
