public abstract class UserMessage
extends Object
```
Common abstract class for holding a text message. This text can be defined in several languages. A message instance has the following features:
- It is displayed according to a given locale (see method formatMessage(Locale)). As each instance is able to hold a specific raw string for various locales, the raw string to be used for display is looked up according to the closest Locale match.
- A message instance may hold parameters. If this is the case, the display uses a limited MessageFormat mechanism to substitute the parameters encoded in the localized raw string. Syntax limitation rules:
  - Format type and style are not managed.
  - Escapes single quote (') using a second one.
  - Escapes entering curly brackets ({) using quote characters ('{').
  - Reverses escape for ('{'[0-9]}) by removing quotes.
- A message instance may hold a Throwable. In this case, the display of the message usually concatenates the throwable stack trace.
- A message instance may also hold a severity. The severity is usually used to categorize the message in the context of a validation.
