8 * The message MUST be a string or object implementing __toString().
9 *
10 * The message MAY contain placeholders in the form: {foo} where foo
11 * will be replaced by the context data in key "foo".
12 *
13 * The context array can contain arbitrary data. The only assumption that
14 * can be made by implementors is that if an Exception instance is given
15 * to produce a stack trace, it MUST be in a key named "exception".
16 *
17 * See https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md
18 * for the full interface specification.
