This is the subtype of the transition.
This must be one of the transition subtypes appropriate for the specified Type
as listed in TransitionSubType.
TransitionSubType::DEFAULT is the default.
Indicates whether the transitionFilter's parent element will transition in or out.
Legal values are true indicating that the parent media will become more visible as
the transition progress increases and false indicating that the parent media will
become less visible as the transition progress increases.
The default value is true.
This specifies the direction the transition will run.
The legal values are true for forward and false for reverse.
The default value is true.
Note that this does not impact the media being transitioned to, but
only affects the geometry of the transition.
Transitions which do not have a reverse interpretation should ignore the
direction attribute and assume the default value of true.
If the value of the Type attribute is TransitionType::FADE and
the value of the Subtype attribute is TransitionSubType::FADETOCOLOR or
TransitionSubType::FADEFROMCOLOR, then this attribute specifies the starting or ending
color of the fade.
The default value is 0 (black).
