XSD/e doesn't really do any buffering during serialization. Once data
is ready, it is written.

I assume you use std::ostream to save the data to a file or similar.
std::ofstream, for example, does some buffering. This page discuss
how you can control it:

Finally, XSD/e provides a low-level writer interface that you can use
instead of std::ostream. This way you will be called every time some
data is available to be written. For more information, see Section 8.1,
"Document Serializer" in the C++/Serializer Getting Started Guide:
