Couple of minor comments:
DBNAME can be included
- * DROP DATABASE [ IF EXISTS ]
+ * DROP DATABASE [ IF EXISTS ] [ [ WITH ] ( options ) ]
can be
- * DROP DATABASE [ IF EXISTS ]
+ * DROP DATABASE [ IF EXISTS ] DBNAME [ [ WITH ] ( options ) ]
Should we include dbname in the below also?
+DROP DATABASE [ IF EXISTS ] <replaceable
class="parameter">name</replaceable> [ [ WITH ] ( <replaceable
class="parameter">option</replaceable> [, ...] ) ]
+
+<phrase>where <replaceable class="parameter">option</replaceable> can
be one of:</phrase>
