If you #import without raw_interfaces_only then the C++ ISaxContentHandler 
class wrapper contains implementations of each of the methods that wrap the 
"raw" implementation, changing COM HRESULTs into C++ exceptions and COM 
automation types (e.g. VARIANT) into C++ wrapper types (e.g. _variant_t). 
These call the raw_ versions of the functions which you implement.

If you don't want this, add raw_interfaces_only after the #import:

#import "MSXML3.dll" raw_interfaces_only

Because MSXML and MSXML2 are not the same thing? You can use no_namespace on 
the #import if you don't want all the interface declarations to be placed in 
a namespace.
