Incorporate Section 10.6 into Section 10.2

• add to section 10.2 (with the new metamodel):

"The equipment element is the main active structure element to model structural physical elements. It is used to model any physical machinery, tools, instruments, or implements. It strictly models the structural aspect of an element; its behavior is modeled by an explicit Assign relationship to the behavior elements. The facility active structure element is used to model the environment in which nodes are deployed or hosted, and equipment is used; for example, office buildings, factories, laboratories, or data centers.

The inter-relationships of physical elements are mainly formed by the logistics infrastructure. The physical realization of a path is modeled with a distribution network; i.e., a physical connection between two or more pieces of equipment or facilities. This can be used to model, for example, rail or road networks, the water supply, power grid, or gas network."
