      public interface XSSimpleType
      extends org.apache.xerces.xs.XSSimpleTypeDefinition

  This interface `XSSimpleType` represents the simple type definition of schema component and defines methods to query the information contained. Any simple type (atomic, list or union) will implement this interface. It inherits from `XSTypeDecl`.

      Returns:
        an ID representing the built-in primitive base type

    - #### validate

        `context` - the validation context
        `validatedInfo` - used to store validation result
      Returns:
        the actual value (QName, Boolean) of the string value
      Throws:

                             throws InvalidDatatypeValueException

      validate a given string value, represented by content.toString(). note that if content is a StringBuffer, for performance reasons, it's possible that the content of the string buffer is modified.
      Parameters:
        `content` - the string value that needs to be validated
        `context` - the validation context
        `validatedInfo` - used to store validation result

        `validatedInfo` - used to provide the actual value and member types
      Throws:
        `InvalidDatatypeValueException` - exception for invalid values.

    - #### applyFacets

          void applyFacets(XSFacets facets,
                           short presentFacet,

                    throws InvalidDatatypeFacetException

      If this type is created from restriction, then some facets can be applied to the simple type. `XSFacets` is used to pass the value of different facets.
      Parameters:
        `facets` - the value of all the facets
        `presentFacet` - bit combination value of the costraining facet constants which are present.
        `fixedFacet` - bit combination value of the costraining facet constants which are fixed.
        `context` - the validation context
      Throws:
        `InvalidDatatypeFacetException` - exception for invalid facet values.

    - #### isEqual

          boolean isEqual(java.lang.Object value1,

      Parameters:
        `value1` - the first value
        `value2` - the second value
      Returns:
        true if the two value are equal

    - #### isIDType

          boolean isIDType()

      Check whether this type is or is derived from ID. REVISIT: this method makes ID special, which is not a good design. but since ID is not a primitive, there doesn't seem to be a clean way of doing it except to define special method like this.
      Returns:
        whether this simple type is or is derived from ID.

    - #### getWhitespace

          short getWhitespace()
                       throws DatatypeException

      Return the whitespace corresponding to this datatype.
      Returns:
        valid values are WS_PRESERVE, WS_REPLACE, WS_COLLAPSE.
      Throws:
        `DatatypeException` - union datatypes don't have whitespace facet associated with them
