W3C validation DOCTYPE warning

I'm getting a doctype warning in the w3c validator for an xhtml page, but my doctype declaration seems to follow the format specified at http://www.w3schools.com/tags/tag_DOCTYPE.asp 

The validation link is http://validator.w3.org/check?uri=http%3A%2F%2Fwww.estores.org.uk%2Findex.php&charset=%28detect+automatically%29&doctype=XHTML+1.0+Transitional&group=0&user-agent=W3C_Validator%2F1.654

The page doctype declaration and warning message is below. Anyone any ideas please?
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" dir="ltr" lang="en">
 
 
 DOCTYPE Override in effect!
 
The detected DOCTYPE Declaration "<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">" has been suppressed and the DOCTYPE for "XHTML 1.0 Transitional" inserted instead, but even if no errors are shown below the document will not be Valid until you update it to reflect this new DOCTYPE.
