CIM_PackagedComponent - A component is typically contained by a physical package, such as a chassis or card. The CIM_PackagedComponent association makes this relationship explicit. In the first sentence, the word, 'typically', is used. This is because a component may be removed from, or not yet inserted into, its containing package (i.e., the Removable boolean property is TRUE). Therefore, a component may not always be associated with a container.

PROPERTY	SMS_REPORT	CIMTYPE	DESCRIPTION
GroupComponent		Reference	The physical package that contains component(s).
LocationWithinContainer		String	A free-form string representing the positioning of the PhysicalElement within the PhysicalPackage. Information relative to stationary elements in the Container (for example, 'second drive bay from the top'), angles, altitudes and other data may be recorded in this property. This string could supplement or be used in place of instantiating the CIM_Location object.
PartComponent		Reference	The physical component which is contained in the package.
