+Common Header - https://msdn.microsoft.com/en-us/library/cc243890.aspx
+8 bytes in total:
+- First byte - Version: Must equal 1
+- Second byte - 1st 4 bits: Endianess (0=Big; 1=Little); 2nd 4 bits: Character Encoding (0=ASCII; 1=EBCDIC)
+- 3rd - Floating point representation (This does not seem to be the case in examples for Microsoft test sources)
+- 4th - Common Header Length: Must equal 8
+- 5th - 8th - Filler: MUST be set to 0xcccccccc on marshaling, and SHOULD be ignored during unmarshaling.
+
+Private Header - https://msdn.microsoft.com/en-us/library/cc243919.aspx
+8 bytes in total:
+- First 4 bytes - Indicates the length of a serialized top-level type in the octet stream. It MUST include the padding length and exclude the header itself.
+- Second 4 bytes - Filler: MUST be set to 0 (zero) during marshaling, and SHOULD be ignored during unmarshaling.
