It's simpler to see the distinction if you first expand the abbreviated syntax. node() doesn't have an explict axis specifier so it is an abbreviation for child::node() so the reason it doesn't match attributes is nothing to do with the node test "node()" it is simply that the test is applied to the child axis, and there are no attributes on the child axis. The same is true of namespace nodes, incidentally. @* is an abbrevation for attribute::* You can see that the node test node() is true for attribute nodes if you apply it to an axis that has such nodes, as in: attribute:node() node() matches attributes in other contexts too, such as the xpath2 expression @foo instance of node() which is true if there is a foo attribute.
