In general I guess I'm not opposed to adding *anything* to the expl3 code while we're playing around with it.

Having said that, I'd say just go for it :) Will --Apple-Mail-1-110755327 Content-Disposition: attachment; filename=smime.p7s Content-Type: application/pkcs7-signature; name=smime.p7s Content-Transfer-Encoding: base64 MIAGCSqGSIb3DQEHAqCAMIACAQExCzAJBgUrDgMCGgUAMIAGCSqGSIb3DQEHAQAAoIIGITCCAtow ggJDoAMCAQICECN4qE5kBXLk2f/jVDfSZPwwDQYJKoZIhvcNAQEFBQAwYjELMAkGA1UEBhMCWkEx JTAjBgNVBAoTHFRoYXd0ZSBDb25zdWx0aW5nIChQdHkpIEx0ZC4xLDAqBgNVBAMTI1RoYXd0ZSBQ ZXJzb25hbCBGcmVlbWFpbCBJc3N1aW5nIENBMB4XDTA5MDEyOTA1NDkxNVoXDTEwMDEyOTA1NDkx NVowQjEfMB0GA1UEAxMWVGhhd3RlIEZyZWVtYWlsIE1lbWJlcjEfMB0GCSqGSIb3DQEJARYQd3Nw cjgxQGdtYWlsLmNvbTCCASIwDQYJKoZIhvcNAQEBBQADggEPADCCAQoCggEBAL0BeSiAbKuqxeRN p2qn/m8ZL+xawr/WXyPgEF0FipWgRe9l3sMXcFHokcUu0xOc97R7xkUsGcQ8EyybGHuWey6x7X1Y xJZXnoAxqcaG+eREytoYGMIKs6BhEEogLVb2ERw3lQNVnOzanSFeGo8suMAN4zzCtqAjJiA1ph7h 1pksTgECYK5EiIZbFsB6zSDa8crNk404z1CfIA6YO8ezvjbDda+D0r8NU2tq9WS9F5IaG+bW71Ya JegEcSZ+WF6Z+fs2MUMCLLu8n50Er0nuy4dxOmkdMRNfbeaM39dsEwjAAgcQnvPNmlJ215nZWQRH 49YowtSBOYUYq0ZylWRE6x8CAwEAAaMtMCswGwYDVR0RBBQwEoEQd3NwcjgxQGdtYWlsLmNvbTAM BgNVHRMBAf8EAjAAMA0GCSqGSIb3DQEBBQUAA4GBABaRP8+PDYpKIRGlFgjs1HvMmJnqu4reSqp+ ulv0zJZIjIbX/sLbIsnecl9nycHfhubPdc+hDfpCqNZ2+NGQHwwoyuDl7KOdTY0BDPp3eJLio7ob EYEr0H8rFwqfx2LWJ0G6nMhNEjLvs7sFKyriSpk++TWJnnsf86xai5m0tlOwMIIDPzCCAqigAwIB AgIBDTANBgkqhkiG9w0BAQUFADCB0TELMAkGA1UEBhMCWkExFTATBgNVBAgTDFdlc3Rlcm4gQ2Fw ZTESMBAGA1UEBxMJQ2FwZSBUb3duMRowGAYDVQQKExFUaGF3dGUgQ29uc3VsdGluZzEoMCYGA1UE CxMfQ2VydGlmaWNhdGlvbiBTZXJ2aWNlcyBEaXZpc2lvbjEkMCIGA1UEAxMbVGhhd3RlIFBlcnNv bmFsIEZyZWVtYWlsIENBMSswKQYJKoZIhvcNAQkBFhxwZXJzb25hbC1mcmVlbWFpbEB0aGF3dGUu Y29tMB4XDTAzMDcxNzAwMDAwMFoXDTEzMDcxNjIzNTk1OVowYjELMAkGA1UEBhMCWkExJTAjBgNV BAoTHFRoYXd0ZSBDb25zdWx0aW5nIChQdHkpIEx0ZC4xLDAqBgNVBAMTI1RoYXd0ZSBQZXJzb25h bCBGcmVlbWFpbCBJc3N1aW5nIENBMIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDEpjxVc1X7 TrnKmVoeaMB1BHCd3+n/ox7svc31W/Iadr1/DDph8r9RzgHU5VAKMNcCY1osiRVwjt3J8CuFWqo/ cVbLrzwLB+fxH5E2JCoTzyvV84J3PQO+K/67GD4Hv0CAAmTXp6a7n2XRxSpUhQ9IBH+nttE8YQRA HmQZcmC3+wIDAQABo4GUMIGRMBIGA1UdEwEB/wQIMAYBAf8CAQAwQwYDVR0fBDwwOjA4oDagNIYy aHR0cDovL2NybC50aGF3dGUuY29tL1RoYXd0ZVBlcnNvbmFsRnJlZW1haWxDQS5jcmwwCwYDVR0P BAQDAgEGMCkGA1UdEQQiMCCkHjAcMRowGAYDVQQDExFQcml2YXRlTGFiZWwyLTEzODANBgkqhkiG 9w0BAQUFAAOBgQBIjNFQg+oLLswNo2asZw9/r6y+whehQ5aUnX9MIbj4Nh+qLZ82L8D0HFAgk3A8 /a3hYWLD2ToZfoSxmRsAxRoLgnSeJVCUYsfbJ3FXJY3dqZw5jowgT2Vfldr394fWxghOrvbqNOUQ Gls1TXfjViF4gtwhGTXeJLHTHUb/XV9lTzGCAxAwggMMAgEBMHYwYjELMAkGA1UEBhMCWkExJTAj BgNVBAoTHFRoYXd0ZSBDb25zdWx0aW5nIChQdHkpIEx0ZC4xLDAqBgNVBAMTI1RoYXd0ZSBQZXJz b25hbCBGcmVlbWFpbCBJc3N1aW5nIENBAhAjeKhOZAVy5Nn/41Q30mT8MAkGBSsOAwIaBQCgggFv MBgGCSqGSIb3DQEJAzELBgkqhkiG9w0BBwEwHAYJKoZIhvcNAQkFMQ8XDTA5MDczMTAwNDEzNVow IwYJKoZIhvcNAQkEMRYEFP+E4M48emeg51YWoOs+LAH5bndyMIGFBgkrBgEEAYI3EAQxeDB2MGIx CzAJBgNVBAYTAlpBMSUwIwYDVQQKExxUaGF3dGUgQ29uc3VsdGluZyAoUHR5KSBMdGQuMSwwKgYD VQQDEyNUaGF3dGUgUGVyc29uYWwgRnJlZW1haWwgSXNzdWluZyBDQQIQI3ioTmQFcuTZ/+NUN9Jk /DCBhwYLKoZIhvcNAQkQAgsxeKB2MGIxCzAJBgNVBAYTAlpBMSUwIwYDVQQKExxUaGF3dGUgQ29u c3VsdGluZyAoUHR5KSBMdGQuMSwwKgYDVQQDEyNUaGF3dGUgUGVyc29uYWwgRnJlZW1haWwgSXNz dWluZyBDQQIQI3ioTmQFcuTZ/+NUN9Jk/DANBgkqhkiG9w0BAQEFAASCAQBiKiRYlppWUK3q/IZS ymTBPrUW/g57/gpW5n1taC4hqwwu9Sq2HFYVfn7BDCHP7iuOI5v8fT/YCnbXTSbmlmIo2X+YTkjW /Qe8ozJbrXdKsp5bltwwHtR3Q6K4YUwMXAAomYNJbNiAObgsRtFPYAJ/7b7u36Pju8niEU/a9/zA KnKtT+QKYTBhM07x9A6l18JpiIZFSa9WskNMXhnJMJ3vlGxOKQK6YbsBGWbCvhtPQ64enhyMR7PX TL9KeslkJV1yphgND2GVXCM591na7PcsU0OiJeMQfGn7vwaLeTtd5k886F3q774SChJWQ+9YeCDA xKq1PpgrpA6bkb5ye3PNAAAAAAAA --Apple-Mail-1-110755327--
