2.1.1 [W3C-XSD] Section, List datatypes


The specification states:

 When a datatype is derived from a list datatype, the following 
 constraining facets apply: 
 • length
 • maxLength
 • minLength
 • enumeration
 • pattern
 • whiteSpace
 For each of length, maxLength, and minLength, the unit of length is measured in 
 number of list items. The value of whiteSpace is fixed to the value collapse.


Other values (preserve or replace) can be assigned to the whiteSpace facet when the base type of the list data type is string.
