The syntax for the filter expressions is shown below.

<FilterExpressionSpec>  ::= <FilterExpression> | ( '(' <FilterExpressionSpec> [ <FilterOperator> <FilterExpressionSpec> ] ')' )
<FilterExpression>      ::= 'All' | <ProtocolTest> | <DataTest> | <IPMatchTest> |
                            <LengthTest> | <ErrorTest> | <PortTest> |
                            <KeyMatchTest> | <KeyTest>
<FilterOperator>        ::= 'AND' | 'OR'
