Where is the documentation for MSXML API?

At microsoft : http://msdn.microsoft.com/en-us/library/ms764730(VS.85).aspx

At DevGuru (updated link): http://www.devguru.com/content/technologies/xml_dom/index.html

http://msdn.microsoft.com/en-us/library/ms763742%28VS.85%29.aspx

I found it be searching on MSDN: http://social.msdn.microsoft.com/Search/en-US?query=msxml.
