Description Konstantin Komissarchik CLA 2010-10-25 18:08:22 EDT 
In some situations it is necessary to be able to stash an arbitrary object
into a property. It could be awkward or difficult to implement string
serialization necessary to do this via a value property.

This comes up in particular when using Sapphire to model an operation or a
small panel inside larger UI. It is frequently necessary in these contexts to
give the model access to some non-serializable objects to provide context.

Sapphire should support a concept of a transient property that can hold an
arbitrary object. Transient properties still need to support change events,
but outside of that no higher-order behaviors would be provided. We would not
support rendering of transient properties in UI. Transient properties would
not interact with the resource (the model element's storage system).
