Help with Xerces-c++

Hi, I need some help with creating the XML declaration. I'm using Xerces-c++ 2.7.0 with MS VC++ 6. When creating an XML file through Xerces, by default it creates the XML declaration like this:

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>

I would like to exclude the encoding and standalone information, so the output of the XML declaration would look like this:

<?xml version="1.0" ?>

I'm able to change the encoding and standalone attributes, but not suppress them. Is there way to exclude them? Any help will be greatly appreciated. Thanks in advanced!
