Enriched textとは 意味・読み方・使い方

Enriched text is a formatted text format for e-mail, defined by the IETF in RFC 1896 and associated with the text/enriched MIME type. It is "intended to facilitate the wider interoperation of simple enriched text across a wide variety of hardware and software platforms". Today, enriched text is almost unknown in e-mail traffic, while HTML e-mail is widely used. Some people see enriched text, or at least the subset of HTML that can be transformed into enriched text, as a superior format for use with e-mail (mainly because of security considerations).
