Proposed resolution for issue 509

[Frank McCabe <frank.mccabe@us.fujitsu.com>]

The issue reads: "What do you mean by function?"

Function, of course, has a mathematical definition. However, we use  
the term in the RM to refer to an operational capability: something  
that can have a real world effect if it is applied.

Proposed resolution:

Either no change to text on the basis that function is a commonly  
understood term in the industry and we do not believe we are using it  
differently.

Or, add a glossary entry:

Function: an operational capability that when activated will result  
in a real world effect.
