PropertyHandle :: ValidateForParent - Is property handle still valid for parent

The function checks, whether the property handle is still valid for the parent property handle passed to the function, i.e. whether the property is a sub-property of the parent. Since parents may move for transient or weak-typed properties, the application must check in case of subordinated property handles, whether those are still valid or not.

When passing true ( YES ) for reopen , the property handle automatically reopens the current property handle for the new parent.
