An enumeration constraint. Syntax is:

 <column one-of="value1,value2,value3..."/>
 

Or:

 <column>
 <one-of [message="error-message"]>
 <value>value1</value>
 <value>value2</value>
 <value>value3</value>
 ...
 </one-of>
 </column>
 

Note: this constraint is not meant to replace an internal SQL enumeration constraint clause in the database, since it cannot be made sure that complex updates will respect this constraint.
