com.cedarsolutions.shared.domain.LocalizableMessage
A message which supports localization.
The simplest message includes just human-readable text. Optionally, you can add a message key and/or indicate which context the message is related to. Both the message key and context are free-form text. This class does not enforce any semantics on these values.

You should always set human-readable text in any message. This text will be used whenever localization is not required (like in log files). The message key and context are optional. If they are provided, they can be used (along with a localization framework) to generate context-sensitive messages to be displayed to a user. For instance, the context could be the field name that a message is related to.
