Why get the error org.xml.sax.SAXParseException when validating the xml in xsd?

Error :

Error - Line 13, 16: org.xml.sax.SAXParseException; lineNumber: 13;
columnNumber: 16; cvc-complex-type.2.4.a: Invalid content was found
starting with element 'me:myself'. One of
'{"urn:Test.Namespace":myself}' is expected.

Test here :

Code:
.xml:

<?xml version="1.0" encoding="utf-8" ?>
