There seems to be an inconsistency in the definition of XQuery Indeed, http://www.w3.org/TR/xpath20/ contains: the following-sibling axis contains the context node's following siblings, those children of the context node's parent that occur after the context node in document order; if the context node is an attribute node or namespace node, the following-sibling axis is empty the ancestor-or-self axis contains the context node and the ancestors of the context node; the following axis contains all nodes that are descendants of the root of the tree in which the context node is found, are not descendants of the context node, and occur after the context node in document order Consider now for instance: <a attr="g"> <b/> </a> clearly <elem>/@attr/following-sibling::node() = empty, <elem>/following-sibling::node() = empty, and <elem>/@attr/following::node() = <b/> But in http://www.w3.org/TR/2004/WD-xquery-semantics-20040220/#sec_axes 4.2.1.1 is written [following:: NodeTest] == [ancestor-or-self::node()/following-sibling::node() /descendant-or-self::NodeTest] Hence by this definition we have <elem>/@attr/following::node() = empty.
