Software is constructed.  Uses emerge, and give rise to systems of 
software components being constructed.  And more uses emerge, and give 
rise to systems composed of systems being constructed.    (03)

We can have software that dynamically finds its counterparts and 
constructs the system it was designed to run, but it doesn't "emerge". 
It was designed and constructed, and the system it was designed to run 
was designed and dynamically constructed.  The only thing that "emerged" 
was the running configuration.    (04)

SOA is not magic.  It is just design principles.    (05)
