Note that for shared parameters IsReadOnly can return false for shared parameters whose UserModifiable property is also false, because the value of those parameters can be modified by the API. If a parameter is governed by a formula, IsReadOnly would return true, even if the flag for UserModifiable was set to true when the shared parameter was created.
