cvc-enumeration-valid: Value is not facet-valid with respect to enumeration

A value is not one of the fixed values the schema allows.

The message, as Java reports it
cvc-enumeration-valid: Value 'closed' is not facet-valid with respect to enumeration '[open, paid]'. It must be a value from the enumeration.

Why it happens

  • A value missing from the list: a new status, a code from a newer code list.
  • A different letter case or surrounding spaces: Paid or " paid" is not paid for a string type.

How to fix it

Use one of the values in brackets, exactly. If a code list was updated, validate against the schema version that has it. Xerces follows this message with cvc-type.3.1.3 naming the element.

Java's schema validation (javax.xml.validation.Validator, and JAXB or Spring on top of it) throws at the first error unless you set an ErrorHandler whose error() records the SAXParseException and carries on; each one has getLineNumber() and getColumnNumber(). A well-formedness error ends parsing whatever the handler does.

The same problem in xmlvalid

xmlvalid validates with libxml2, which reports it as [facet 'enumeration'] The value is not an element of the set. It checks the whole document in your browser and lists every schema error with its line and column, not only the first.

Element 'status': [facet 'enumeration'] The value 'closed' is not an element of the set {'open', 'paid'}.

Validated against order.xsd, below.

Reports the error
<order currency="EUR">
  <id>A-1</id>
  <qty>1</qty>
  <status>closed</status>
</order>
Fixed
<order currency="EUR">
  <id>A-1</id>
  <qty>1</qty>
  <status>paid</status>
</order>
