The PROP_TAG macro creates a property tag for a property of type ulPropType and the identifier that is specified in ulPropID. For example, a property tag for an entry identifier can be created with the PROP_TAG macro as follows:

PROP_TAG( PT_BINARY, 0x0FFF)

The low-order 16 bits of the returned property tag contain the property type, PT_BINARY, and the high-order 16 bits contain the property identifier, 0xFFFF.
