MS SAX2 XML implementation bugs?

Is it a bug in Microsoft’s SAX2 API:

It seems “characters” event is generated only once after new element is found
example:

1 – “characters” event is generated
2 – “characters” event is NOT generated

I tested with Microsoft’s SAX2 JumpStart app for VC++. Just implement “Characters” event in MyContent class in the same way as StartElement event. I used MSXML SDK 3.0. Any ideas?
