Attribute	Values
CO_MARSHALING_SOURCE_IS_APP_CONTAINER	This attribute is a boolean value, with 0 representing TRUE and nonzero representing FALSE. You can safely cast the value of the result to BOOL, but it isn't safe for the caller to cast a BOOL* to ULONG_PTR* for the pAttributeValue parameter, or for the implementation to cast pAttributeValue to BOOL* when setting it.
