Class Length

Object
  extended by Length

public abstract class Length
extends Object

length is the number of units of length, where units of length varies depending on the type that is being ???derived??? from.

The value of length ???must??? be a nonNegativeInteger.

Length is defined as: This is xml so length string applies to datatypes derrived from string.

Simon the spec says: For string and datatypes ???derived??? from string, length will not always coincide with "string length" as perceived by some users or with the number of storage units in some digital representation. Therefore, care should be taken when specifying a value for length and in attempting to infer storage requirements from a given value for length.

Example:


 <simpleType name='productCode'>
  <restriction base='string'>
    <length value='8' fixed='true'/>
  </restriction>
 </simpleType>
