[AccessD] Reference, Property, Kind, constants?

Hi all

Anyone familiar with the VBE constants for the "Kind" property of a
reference?             

It can be 0 or 1.

Two constants are listed at Microsoft:

vbext_rk_TypeLib and vbext_rk_Project,

but these are neither recognised by my Access 97 nor Access 2002.
Is this an Access 2003 speciality?
