| angleExpressionInfo | This expressionInfo object allows specifies how the angle (in degrees) for a label is calculated from the feature attributes. It may use attributes, fixed numbers, or a combination of both. If missing, an angle value of zero is assumed. |
| rotationType | Optional specification of whether the placement angle calculated by the angleExpressionInfo should be interpreted as arithmetic (counter-clockwise from East) or geographic (clockwise from North).Valid values:
