4.1.6 Context

Cleared out "fluffy language".  Added clarity to registration (check please).  Removed numerical references and replaced with topical. Removed in-section references. Applied organization similar to 4.1.x sections.  Separated requirements from tables.  Eliminated Example 1 as it had no words with it and didn't seem to add value.
Eliminated "Person" added necessarily confined
