Description

xs:enumeration is a facet that allows definition of a list of possible values for the value space of a datatype by enumerating all these values in separated xs:enumeration elements in a single restriction step (i.e., under a single rs:restriction parent element). This is one of the two facets (with xs:pattern) that are available for all the datatypes (atomic, lists, or unions), but unlike xs:pattern, xs:enumeration is not available for xs:boolean.

Restrictions

The values of the xs:enumeration facets must belong to the value space of the base datatype. When the base datatype is already restricted by ...
