SACM — Eliminate or change name of “EffectiveTime"

"EffectiveTime" is not an obvious term. This class might be best eliminated and its subclasses have TimingProperty as their superclass, or a more understandable name should be used.

Change text of section 13.2.2, page 58, from
EffectiveTime element is an abstract class that corresponds to effective time interval
associated with the owner element. This element was added for readability purposes.
into
EffectiveTime element represents various compound statements that involve a certain
time interval during which a certain proposition is asserted to be true (time-dependent
assertions involving an "effective" time period).
Change text of the semantics section on page 58 from:
Semantics
EffectiveTime element represents a property of the owner EvidenceElement object or
EvidenceAttribute object. This element is an abstract class that establishes a relationship
between the owner object and the detailed of the effective time interval of the owner
object, defined by a particular concrete subclass of the TimingProperty element.
into
Semantics
EffectiveTime element represents a statement about the subject EvidenceElement (an
object that owns the instance of one of the concrete subclasses of this element). The
EffectiveTime element specifies a time interval associated with the subject, during which
the subject is asserted to be "effective". For example, in case of an EvidenceAssertion or
a FormalAssertion, this element specifies a time interval at which the corresponding
statement is asserted to be true. In case on am EvidenceItem this element specifies the
relevant time context in which the element shall be considered.
