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.
