7. List of Statements

This section defines in summary format all the statements available in BIND 
9.3.0 (updated for some 9.10.x values) named.conf. This list is in alphabetic 
order to make it useful. Don't you just hate it when you spend two minutes 
looking for something that should take two seconds. The entries enclosed in 
square brackets following the statement, and where present, specify the clause 
or clauses in which the statement may be used. Progressively we are adding the 
default value in bold where it is clear and unambiguous.
