# This class ensures that the RELS-EXT datastream is always serialized
# with an rdf:Description container for the properties
# the default behavior for RDF:RDFXML::Writer is to change that element if
# an rdf:type assertion is present; this is incompatible with Fedora 3

#
# If the Haml template contains an entry matching the subject's rdf:type URI, that entry will be used as the template for this subject and it's properties.

# @example Displays a subject as a Resource Definition:
# <div typeof="rdfs:Resource" about="http://example.com/resource">
# <h1 property="dc:title">label</h1>
# <ul>
# <li content="2009-04-30T06:15:51Z" property="dc:created">2009-04-30T06:15:51+00:00</li>
# </ul>
# </div>
#
# @param [RDF::Resource] subject
# @param [Hash{Symbol => Object}] options
# @option options [:li, nil] :element(:div)
# Serialize using <li> rather than template default element
# @option options [RDF::Resource] :rel (nil)
# Optional @rel property
