public interface SchemaComponent
```
This is a marker interface that represents any "schema component" as defined in the XML Schema specification. This may be a user-defined schema component or a built-in schema component. Since all built-in schema components are types, every SchemaComponent in practice is either a com.saxonica.ee.schema.UserSchemaComponent or a SchemaType or both.

- Method Detail
  - getValidationStatus
```
SchemaValidationStatus getValidationStatus()
```
    Get the validation status of this component.
    
    Returns:
    
    one of the values SchemaValidationStatus.UNVALIDATED, SchemaValidationStatus.VALIDATING, SchemaValidationStatus.VALIDATED, SchemaValidationStatus.INVALID, SchemaValidationStatus.INCOMPLETE
  - getRedefinitionLevel
```
int getRedefinitionLevel()
```
    Get the redefinition level. This is zero for a component that has not been redefined; for a redefinition of a level-0 component, it is 1; for a redefinition of a level-N component, it is N+1. This concept is used to support the notion of "pervasive" redefinition: if a component is redefined at several levels, the top level wins, but it is an error to have two versions of the component at the same redefinition level.
    
    Returns:
    
    the redefinition level
