I havent yet tried the code, looks fine though, and was going to do some 
consolidation on it first
i.e. xmlOutputBufferCreateBuffer calling xmlOutputBufferCreateIO and 
xmlNewTextWriterMemory calling xmlOutputBufferCreateBuffer.

Is there any reason why xmlTextWriterWriteMemCallback always returns len 
and doesnt do an error check? In the event of an error writing to the 
buffer it looks like this would be wrong not to signal an error.
