2.1.1 [W3C-XSD] Section 18.104.22.168, 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 (
replace) can be assigned to the whiteSpace facet when the base type of the list data type is string.
