Change superclass of EvidenceProperty to 'EvidenceAssertion'
Change description of the EvidenceProperty element from
EvidenceProperty is an abstract class that represents various parts of the primary
evidence elements.
into
EvidenceProperty represents various statements related to the fundamental properties of
evidence elements.
Change the semantics subsection of EvidenceProperty from EvidenceProperty is owned by various Element as appropriate. EvidenceProperty
represents fundamental properties of the EvidenceElement, as opposed to
EvaluationAttribute, which represent assertions that potentially can be disputed.
EvidenceProperty involves one or more subjects, specified either as attributes or the
associations of the EvidenceProperty element. Each EvidenceProperty represents a
relationship between the Element that owns it and its subject.
