Gets or sets a value that indicates whether this property contains journaling information that applications can or should store as part of a journaling implementation.
Assembly: PresentationFramework (in PresentationFramework.dll)
The metadata has already been applied to a dependency property operation, so that metadata is sealed and properties of the metadata cannot be set.
Properties on derived classes of PropertyMetadata are typically defined in the object model as read-write. This is so they can be adjusted after initialization of the instance. However, after the metadata is consumed as part of a call to Register, AddOwner, or OverrideMetadata, the property system will seal that metadata instance and properties that convey the specifics of the metadata are now considered immutable. Attempting to set this property after IsSealed is true on this metadata instance will raise an exception.
Members of this class are not typically used in XAML.
