+Inserts are documents prepared solely for the purpose of being incorporated into one or more master documents. They resemble regular SiSU text files (.sst). Since sisu-5.5.0 (6.1.0) .ssi files can like .ssm files include other .sst or .ssm files. .ssi files cannot be called by the sisu processor directly and can only be incorporated in other documents. Making a file a .ssi file is a quick and convenient way of breaking up a document that is to be included in a master document, and flagging that the file to be incorporated .ssi is not intended that the file should be processed on its own.
