Add this step to the RDF section:

]]
For each img and iframe element in the Document that has a longdesc attribute
that resolves successfully relative to the element, generate the following
triple:

subject
    the document's current address 
predicate
    http://www.w3.org/2007/05/powder-s#describedby
object
    the absolute URL that results from resolving the value of the element's
longdesc attribute relative to the element

Citing POWDER:

]] 2.2.8 Property describedby

RDF Property

Label: described by

Defined in: http://www.w3.org/TR/powder-dr/#semlink

An RDF property to exactly match the describedby relationship type introduced
in http://www.w3.org/TR/powder-dr/#assoc-linking and formally defined in
appendix D of the same document, i.e. the relationship A 'describedby' B
asserts that resource B provides a description of resource A. There are no
constraints on the format or representation of either A or B, neither are there
any further constraints on either resource
