SG1 subsequently agreed to update the draft ATSMHS SARPs such that both ISO 646 and optionally ISO 8859-1 text messages should also be conveyed by AFTN/AMHS Gateways. Unfortunately, the result of the SARPs update is incomplete in the following areas: a. The implicit-conversion-prohibited per-message-flag, if set to prohibited, should only cause the message to be rejected by the AFTN/AMHS Gateway if, and only if, the EITs indicate that the message contains an ISO 8859-1 text bodypart (including the ATS-Message-Text). b. The list of "acceptable" EITs should be those corresponding to the following body part types: IA5 Text (either basic and externally-defined), General Text (externally-defined - ISO 646), and optionally General Text (externally-defined - ISO 8859-1). Assigned SME: Sub-Volume 3 SME Proposed SARPs amendment : A) move entire clause 3.1.2.3.5.2.1.2 ahead of clause 3.1.2.3.5.2.1.1 and renumber both clauses accordingly. B) in the new clause 3.1.2.3.5.2.1.1, replace the words: "A message which was not rejected as the result of 3.1.2.3.5.2.1.1" to read "Upon reception by the Message Transfer and Control Unit of an IPM, the received message" C) in the new clause 3.1.2.3.5.2.1.2, replace the words: "Upon reception by the Message Transfer and Control Unit of an IPM conveyed with a Message Transfer Envelope, the received message" to read "A message which was not rejected as the result of 3.1.2.3.5.2.1.1" D) amend the text of item a) of new clause 3.1.2.3.5.2.1.1, which is currently: "a) processing as specified in 3.1.2.3.5.2.1.3 if the abstract-value of the encoded-information-types is "ia5-text" or extended "ia5-text"; or" to read the following text: "a) processing as specified in 3.1.2.3.5.2.1.2 if the abstract-value of the encoded-information-types is any of the following : 1) basic "ia5-text"; 2) externally-defined "ia5-text"; 3) OID {id-cs-eit-authority 1}; 4) OID {id-cs-eit-authority 2}; 5) OID {id-cs-eit-authority 6}; or 6) OID {id-cs-eit-authority 100}; or" E) amend the text of item b) of new clause 3.1.2.3.5.2.1.1, which is currently: "b) if the abstract-value differs from built-in "ia5-text" and from extended "ia5-text":" to read the following text: "b) if the abstract-value differs from all values indicated in item a) above:" F) amend the text of item a) of new clause 3.1.2.3.5.2.1.2, by replacing the current cross-reference to 3.1.2.3.5.2.1.2 by a new cross-reference to 3.1.2.3.5.2.1.3. G) amend the text of item b) of new clause 3.1.2.3.5.2.1.2, which is currently: "b) if the abstract-value of the element is "prohibited":" to read the following text: "b) if the abstract-value of the element is "prohibited" and if the abstract-value of the encoded-information-types includes OID { id-cs-eit-authority 100}:" SME Recommendation to CCB: RESOLVED CCB Decision: RESOLVED
