XSD enumerations: key value pairs
Posted by jpluimers on 2016/04/26
One of the things you cannot do in XSD, is have string enumerations contain both a key and a value.
But there is a little appinfo trick inside annotation that you can user under some circumstances, for instance when you interpret the XSD:

| <xs:simpleType name="event_result"> | |
| <xs:restriction base="xs:string"> | |
| <xs:enumeration value="101"> | |
| <xsd:annotation><xsd:appinfo>Syntax error</xsd:appinfo></xsd:annotation> | |
| </xs:enumeration> | |
| <xs:enumeration value="102"> | |
| <xsd:annotation><xsd:appinfo>Illegal operation</xsd:appinfo></xsd:annotation> | |
| </xs:enumeration> | |
| <xs:enumeration value="103"> | |
| <xsd:annotation><xsd:appinfo>Service not available</xsd:appinfo></xsd:annotation> | |
| </xs:enumeration> | |
| </xs:restriction> | |
| </xs:simpleType> |
appinfo is the application counterpart of documentation: both can contain any xml, but appinfo is aimed at machines, whereas documentation is aimed at humans.
