The Standard Generalized Markup Language (SGML) community is actively addressing certain issues that relate to interoperability but not those directly related to electronic mail. This working group will address e-mail issues and concerns to directly support the exchange of SGML in MIME e-mail. These issues include the structure of MIME document that will contain both SGML document markup and the various definitions, including handling of public and private identifiers. The working group's effort is NOT intended to address the syntax and structure of SGML. Previous work in this area, ISO 9069, SGML Document Interchange Format (SDIF) and SGML Open Technical Resolution 9401 will be addressed as interface requirements that may be supported through e-mail.
