ElementDecl

```
public interface ElementDecl
```
represents a constraint for one XML element. One can obtain an IslandVerifier that validates this constraint by calling createNewVerifier method of IslandSchema who exported this object. This interface also provides feature/property mechanism to encourage communications between two different implementations.
