Explanation:
An Active Directory Lightweight Directory Services (AD LDS) schema defines, using object classes and attributes, the types of objects and data that can be created
and stored in an AD LDS directory. The schema can be extended with new classes and attributes, either by administrators or by the applications themselves. In
addition, unneeded schema classes and attributes can be deactivated.http://technet.microsoft.com/en-us/library/cc771975.aspx http://technet.microsoft.com/en-us/library/cc731547.aspx
this is correct. Just to complete your comment, the property you want to look for in SCHEMA context is “isMemberOfPartialAttributeSet”, which indicates if a property is replicated to GC.
