"More than 40 years have passed since the U.S. government decided to go metric; yet, many in the U.S. moldmaking industry still hang on to the imperial system, leaving some baffled as to how and when we will see a complete conversion.  It does not matter what it is we seek to change, a few simple rules apply in our decision process. It is not just a rejection of metric, it is a rejection of any change that these rules apply."^^<http://www.w3.org/2001/XMLSchema#string>
