# I agree that the prose and formal meanings  of the following expression
# conflict, but I believe the formal semantics is the correct one, i.e.,
# $x/@attr/following::node() = ()

The XPath 1.0 definition is:

"the following axis contains all nodes in the same document as the context
node that are after the context node in document order, excluding any
descendants and excluding attribute nodes and namespace nodes"

(The accepted meaning of "any descendants" is "descendants of the context
node", while the accepted meaning of "attribute nodes and namespace nodes"
is "all attribute and namespace nodes")

This definition means that the following axis, starting at an attribute,
includes the children of the element containing that attribute.
