The best resource to find out what program does is sources. Take a look at 
Saxon's, Xalan's, .NET XslTransform's etc source codes.
Also read famous "Saxon: Anatomy of an XSLT processor" by Michael Kay

Depends on implemenatation, but the conceptual data model is described in 
XPath spec: http://www.w3.org/TR/xpath#data-model.
