'xs:token with single spaces': {|xml|| <token>This is a sentence.</token> |}. 'xs:token with empty value': {|xml|| <token></token> |}. % the following test cases would theoretically fail, but the whitespaces get replaced while parsing 'xs:token with leading space': {|xml|| <token> This is a string!</token> |}. 'xs:token with trailing space': {|xml|| <token>This is a string! </token> |}. 'xs:token with multiple spaces in-between': {|xml|| <token> This is a string!</token> |}.
