An entire specification can be decomposed into children requirements, which can be further decomposed into their children to define the requirements hierarchy. Source OMG Systems Modeling Language (SysML) 1.6
A composite requirement may state that the system shall do A and B and C, which can be decomposed into the child requirements that the system shall do A, the system shall do B, and the system shall do C Source OMG Systems Modeling Language (SysML) 1.6
A composite requirement can contain subrequirements in terms of a requirements hierarchy, specified using the UML namespace containment mechanism. This relationship enables a complex requirement to be decomposed into its containing child requirements. Source OMG Systems Modeling Language (SysML) 1.6
