Incidentally, I was at one time under the impression that: following::X ==> ancestor-or-self::node()/following-sibling::node()/descendant-or-self::X but unfortunately this breaks when starting at attributes or namespaces But I think the corresponding equation preceding::X ==> ancestor-or-self::node()/preceding-sibling::node()/descendant-or-self::X is valid. To make the first equation true you have to have to define a new axis following::X ==> ancestor-or-self::node()/following-duckling::node()/descendant-or-self::X where the ducklings of a node N are all the children of the parent of N (even when N is an attribute or namespace).
