Node that maps a subtree in the source XML to a Ruby object. :attrname and path are again the attribute name resp. XPath expression of the mapped attribute; the keyword arguments :default_value and :optional are handled by the SingleAttributeNode superclass. The XML subnode named by path is mapped to the attribute named by :attrname according to the keyword arguments :class, :marshaller, and :unmarshaller, which are handled by the SubObjectBaseNode superclass.
