Block extensions (non-normative)

As recommended through SysML1.0 examples:

• «system» top-level block to be used in a system context
• «subsystem» grouping (usually physical) within a system
• «external» outside the top-level system (yet affecting it)
• «domain» provides a common context for a system and externals
• «system context» a particular context for a system and externals
