Public Class PropertyMetadata
Property metadata can be defined and used during dependency property registration when calling the Register method (or variations for attached properties or read-only dependency properties), or after original owner registration when calling the OverrideMetadata method. AddOwner also takes property metadata.
This class is a concrete base class that can be used in each of these calls. However, it is very common to specify metadata using one of the derived classes such as FrameworkPropertyMetadata. These derived classes support more detailed metadata carried as Boolean property values, which are useful for either detecting or enabling some property system and layout behaviors that are only implemented at the WPF framework level.
Several properties of this class are read-write to the object model, but can only be written prior to the instance being used in a property system operation such as Register or OverrideMetadata. Each of these properties could also have been set by the constructor but are exposed so that Merge method implementations can set them.
