# There is no real data definition for this class - it consists entirely of GUIDs.
#
# struct GUID - GUID structures store globally unique identifiers (GUID).
#
# A GUID is a 128-bit value consisting of one group of eight hexadecimal
# digits, followed by three groups of four hexadecimal digits each, followed
# by one group of twelve hexadecimal digits. GUIDs are Microsoft's
# implementation of the distributed computing environment (DCE) universally
# unique identifier (UUID).
#
# Example of a GUID:
# 1F010768-5A73-BC91-0010-A52216A7227B
