Type: System.Windows.DependencyProperty

The dependency property to which the metadata has been applied.

Type: System.Type

The type associated with this metadata if this is type-specific metadata. If this is default metadata, this value is a null reference.

Subclasses should assure that any mutability of the data structure of a PropertyMetadata subclass should be marked as immutable once OnApply is called. This will be called once the metadata is applied to a property system operation (register, add owner, override metadata).
