Expand description

Context payload that is injected as a message fragment.

Implementations own the response role and provide the exact fragment body. Marked fragments also provide start/end markers used to recognize injected context later. render() concatenates markers and body without adding separators, so implementations should include any whitespace they need between tags in body(). Unmarked fragments should leave both markers empty, in which case the default helpers render only the body and never match arbitrary text.
