I tracked this down a little bit farther.  The error occurs when I change the default COLUMN_DELIMITER from Chr(17) to something else.  Using Chr(17) causes the page to fail xhtml validation.  Using other characters causes the previously posted error to occur.

I have gotten around this by changing the ClientAPICaps.config file as follows:
    <functionality nm="SingleCharDelimiters" desc="Supports single character delimiters (i.e. Char(18))">
        <supports>
        </supports>
        <excludes>
            <browser nm="*" />
        </excludes>
    </functionality>   

That seems to take care of this issue.  Any caveats to using this approach?

Thanks,

The error message is outlined at:
http://validator.w3.org/docs/errors.html

It is "410: reference to non-SGML character".  The page is using UTF-8 encoding.

Perhaps selecting a different encoding type would eliminate the validation error?

For reference, the site I am working on is posted at: http://motorsports.promediagroup.com.  It is currently set to use the 3 character delimiter.  I don't have anything that is publicly viewable that uses Chr(17) which will trigger the validation error.  If you think it would be helpful, let me know and I'll try to post something.

Thanks,
Eric
