That's an argument in favour of allowing links to be to named flow objects,
which can easily added: eg add an address flow object and
flow-object-address procedure.  It's not an argument in favour of
disallowing links to nodes, which would require style-sheets to continually
invent names for flow objects, and wouldn't work for links outside the
current flow object tree.  Not to mention the serious backward compatibility
problems that would cause.
