Method Summary
`XSSimpleType` `createTypeList(java.lang.String name, java.lang.String targetNamespace, short finalSet, XSSimpleType itemType, org.apache.xerces.xs.XSObjectList annotations)` Create a new simple type which is derived by list from another simple type.
`XSSimpleType` `createTypeRestriction(java.lang.String name, java.lang.String targetNamespace, short finalSet, XSSimpleType base, org.apache.xerces.xs.XSObjectList annotations)` Create a new simple type which is derived by restriction from another simple type.
`XSSimpleType` `createTypeUnion(java.lang.String name, java.lang.String targetNamespace, short finalSet, XSSimpleType[] memberTypes, org.apache.xerces.xs.XSObjectList annotations)` Create a new simple type which is derived by union from a list of other simple types.
`XSSimpleType` `getBuiltInType(java.lang.String name)` Get a built-in simple type of the given name REVISIT: its still not decided within the Schema WG how to define the ur-types and if all simple types should be derived from a complex type, so as of now we ignore the fact that anySimpleType is derived from anyType, and pass 'null' as the base of anySimpleType.
`SymbolHash` `getBuiltInTypes()` get all built-in simple types, which are stored in a hashtable keyed by the name

### BaseDVFactory

    public BaseDVFactory()

Method Detail

### getBuiltInType

    public XSSimpleType getBuiltInType(java.lang.String name)

  Get a built-in simple type of the given name REVISIT: its still not decided within the Schema WG how to define the ur-types and if all simple types should be derived from a complex type, so as of now we ignore the fact that anySimpleType is derived from anyType, and pass 'null' as the base of anySimpleType. It needs to be changed as per the decision taken.
  Overrides:
    `getBuiltInType` in class `SchemaDVFactory`
  Parameters:
    `name` - the name of the datatype
  Returns:
    the datatype validator of the given name

### getBuiltInTypes

    public SymbolHash getBuiltInTypes()

  get all built-in simple types, which are stored in a hashtable keyed by the name
  Overrides:
    `getBuiltInTypes` in class `SchemaDVFactory`
  Returns:
    a hashtable which contains all built-in simple types

### createTypeRestriction

    public XSSimpleType createTypeRestriction(java.lang.String name,
                                              java.lang.String targetNamespace,
