Properties

	Name	Description
	CommandParameter	Gets or sets the command parameter.
	CommandSource	Gets or sets the type of the command source factory defining the command.
	CommandTarget	Gets or sets the command target.
	CompositionContext	Gets or sets the composition context.
	IsActive	Gets a value indicating whether this instance is active. If multiple command routings exist, the routing of the element that had the most recent keyboard focus is active.
	IsChecked	Gets or sets a value indicating whether this instance is checked, e.g. when bound to a MenuItem with IsCheckable set to true.
	IsEnabled	Gets or sets a value indicating whether this instance is enabled, i.e. if the routing will be active. This does not affect the enabled state of the visual bound to the command source.
