Gets or sets the marker type of a TimelineMarker.
When the TimelineMarker represents a Windows Media marker, this property is set to "Name". When the TimelineMarker represents a script command, this property contains the value of its "Type" field.
The XAML syntax for TimelineMarker is mainly relevant only for a CreateFromXaml scenario. Populating the initial .Markers collection in XAML is permitted by the parser, but it has no effect because the .Markers collection is specific to a media source instead of a MediaElement. For more information, see TimelineMarker.
