  - getDescription
```
public String getDescription()
```

    Ask whether this type is an ID type. This is defined to be any simple type who typed value may contain atomic values of type xs:ID: that is, it includes types derived from ID by restriction, list, or union. Note that for a node to be treated as an ID, its typed value must be a *single* atomic value of type ID; the type of the node, however, can still allow a list.

    isIdType in interface SchemaType
    
    Returns:
    true if this type is an ID type

```
    Check whether a given input string is valid according to this SimpleType
    
    Specified by:
    
    validateContent in interface SimpleType
    
    Parameters:
    value - the input string to be checked
    nsResolver - a namespace resolver used to resolve namespace prefixes if the type is namespace sensitive. The value supplied may be null; in this case any namespace-sensitive content will throw an UnsupportedOperationException.
    rules - conversion rules e.g for namespace-sensitive content
    
    Returns:
    XPathException if the value is invalid. Note that the exception is returned rather than being thrown. Returns null if the value is valid.
    
    Throws:

    getStringConverter in interface AtomicType
    
    Parameters:
    rules - the conversion rules to be used

    Returns:
    the typed value.
    
    Throws:
    
    XPathException - if the node cannot be atomized, for example if this is a complex type with element-only content
    Since:

    Specified by:
    
    getTypedValue in interface SimpleType
    
    Parameters:

    Throws:
    
    ValidationException - This method should be called only if it is known that the value is valid. If the value is not valid, there is no guarantee that this method will perform validation, but if it does detect a validity error, then it MAY throw a ValidationException.
  - equals
```
public boolean equals(Object obj)
```
    Two types are equal if they have the same fingerprint. Note: it is normally safe to use ==, because we always use the static constants, one instance for each built in atomic type. However, after serialization and deserialization a different instance can appear.
    
    Overrides:
    
    equals in class Object
  - hashCode
```

    The fingerprint can be used as a hashcode

  - getComponentAsFunction
```
public Function getComponentAsFunction()
```
    Description copied from interface: SchemaComponent
    
    Get the schema component in the form of a function item. This allows schema information to be made visible to XSLT or XQuery code. The function makes available the contents of the schema component as defined in the XSD specification. The function takes a string as argument representing a property name, and returns the corresponding property of the schema component. There is also a property "class" which returns the kind of schema component, for example "Attribute Declaration".
    
    Specified by:
    
    getComponentAsFunction in interface SchemaComponent
    
    Returns:
    the schema component represented as a function from property names to property values.
