What is the common XML API in Win32 platform?

I'm implementing a RELAX NG validator for Win32 platform,
but I wonder which API I should target to.

What is the API people tend to use in VC++/VB/Delphi world?
Are people using MSXML DOM? MSXML SAX? or Xerces-C?

When I was working on Win32, the only API available in MSXML was DOM.
But I suppose things has changed considerably during this one or two
years.


Any feedback would be greatly appreciated.
