FOR XML SQL Query to generate a Record Header - sql

Question

I am trying to generate a XML using FOR XML SQL Query. Structure of the XML is pretty straight forward, except the requirement calls for an extra sub-element, which has to appear only once at the top of the document between the Root Element and record element. Here is an example:
<Employees xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<RecordHeader>
<CreatedBy>My Organization</CreatedBy>
<CreateDate>1900-01-01T01:01:01-06:00</CreateDate>
</RecordHeader>
<Employee>
<EmployeeID>4</EmployeeID>
<FirstName>Rob</FirstName>
<LastName>Walters</LastName>
</Employee>
<Employee>
<EmployeeID>168</EmployeeID>
<FirstName>Rob</FirstName>
<LastName>Caron</LastName>
</Employee>
</Employees>
I created a FOR XML Query but I can't seem to get it to work properly for the RecordHeader. Any suggestions? Thanks!
SELECT
(SELECT 'My Organization' as [CreatedBy],
CONVERT(VARCHAR(33), GetDate(), 126) as [CreateDate] FOR XML PATH('RecordHeader'), ELEMENTS),
EmployeeID, FirstName, LastName
FROM Employees
FOR XML PATH('Employee'), ROOT('Employees'), ELEMENTS

Declare #Employee table (EmployeeID int,First_Name varchar(50),Last_Name varchar(50))
Insert into #Employee values
(1,'John','Smith'),
(2,'Jane','Doe' )
Select (Select CreatedBy='My Organization',CreateDate=GetDate() For XML Path('RecordHeader'),Type )
,(Select * From #Employee For XML Path('Employee'),Type )
For XML Path ('Employees'),Type
Returns
<Employees>
<RecordHeader>
<CreatedBy>My Organization</CreatedBy>
<CreateDate>2016-10-18T16:09:48.110</CreateDate>
</RecordHeader>
<Employee>
<EmployeeID>1</EmployeeID>
<First_Name>John</First_Name>
<Last_Name>Smith</Last_Name>
</Employee>
<Employee>
<EmployeeID>2</EmployeeID>
<First_Name>Jane</First_Name>
<Last_Name>Doe</Last_Name>
</Employee>
</Employees>
