Invalid data

When a data object does not match the definition of the type to which it presumably belongs, it could be invalid.

Possible reasons for an invalid data object:

• Item value is not in restriction list
• Item failed the presentation test
• Item is the wrong size
• Data object has the wrong delimiter
• Data object has the wrong terminator
• Data object failed the component rule
• Group is missing a required component
• Group contains one or more invalid component(s)
