Errors with = and ~ for date and datetime

[richardtownleyoneill-ADHA]

The following expressions return results different to what I expect from the docco at http://hl7.org/fhirpath/#operations

@T10:30:31=@T10:30		//False, should be { }
@T10:30:31~@T10:30		//True, should be { }

{ } = ‘a’							// True, should be { }
@2012-01 = @2012					// False, should be { }
@2012-01 ~ @2012					// True, should be False
@2012-01-01T10:30 = @2012-01-01T10:30		//syntax error, should be True
@2012-01-01T10:30 = @2012-01-01T10:31		//syntax error, should be False
@2012-01-01T10:30:31 = @2012-01-01T10:30		//syntax error, should be { }
