Minor changes on Section 10.3.3

For better readability:

• from "A technology collaboration, or two or more nodes, may be assigned..." to "A technology collaboration, or two or more technology internal active structure elements, may be assigned ..."
• from "A technology interaction may realize technology services and technology services may serve a technology interaction." to "A technology interaction may realize technology services."
• add this sentence just after the previous one: "Business, application, and technology services may serve a technology interaction."
• from "A technology interaction may access artifacts." to "An application interaction may access application passive structure elements."
