Create MIME Containing XML

Calls SetBodyFromXml to load XML into the MIME body. Also sets the Content-Type header to "text/xml", and the Content-Transfer-Encoding to an appropriate transfer encoding based on the characters found in the XML.

    EXEC sp_OAMethod @mime, 'GetMime', @sTmp0 OUT

    --  The MIME should look like this:
    --  
Description: this is a test
MyId: 123
Content-Type: text/xml; 
Content-Transfer-Encoding: 7bit

<something>123</something>

    --  Note: The Content-Transfer-Encoding may be changed.
    --  For example, to use "base64", do this:
    EXEC sp_OASetProperty @mime, 'Encoding', 'base64'

    --  Show the MIME again, this time using the base64
    --  transfer encoding:
    EXEC sp_OAMethod @mime, 'GetMime', @sTmp0 OUT
    PRINT @sTmp0

    --  It should look like this:
    --  
Description: this is a test
MyId: 123
Content-Type: text/xml; 
Content-Transfer-Encoding: base64
