public interface PropertyName

```
Expression class whose value is computed by retrieving the value indicated by the provided name.
The most common applicatoin of this is to retrive a feature's property using an xpath expression.
Please note that the Filter specification allows a limited subset of XPath to be used for the PropertyName. We encourage implementations to match this functionality.
