what exactly is a node ?

Hello,

It's unclear to me what exactly can a "node" be, in the sense of the
XPath specs.
So: "XPath models an XML document as a tree of nodes. There are
different types of nodes, including element nodes, attribute nodes and
text nodes".

What else ? Entity nodes ? Namespace declaration nodes ?
Everything that is a node from a DOM point of view ? If yes, why is it
not mentioned ?

If an XML file contains a "CR, LF, blank, blank" sequence, does that
account for a text node or not ?

Thank you,
