This error message means what it says, and explains what the
preceding, less clear, error message means:  You haven't provided any
information (e.g. a schemaLocation attribute on your xs:import) about
where to find a schema document for the
http://www.w3.org/2000/09/xmldsig# namespace.  As a result, the
reference to a Signature element in that namespace fails.

Try adding

schemaLocation="http://www.w3.org/TR/2002/REC-xmldsig-core-20020212/xmldsig-core-schema.xsd"

to your xs:import.
