URIs should be in the form:
If you entered a valid URI using a scheme that we should support, please let us know as outlined on our Feedback page. Make sure to include the specific URI you would like us to support, and if possible provide a reference to the relevant standards document describing the URI scheme in question.
I assume that this is because the page is local to my computer and
does not have a URI which is accessible to the validator. Is there any
possibility of a fix or workaround. I would appreciate it if a
potential employer who I sent my C.V. to in XHTML would be able to
click on the button and see that it is valid markup instead of an error
