In Word, you can create a master document that contains links to sub-documents. When the master document is opened or printed, it pulls the content from the sub-documents and creates a single document. One of the issues with this is that the sub-documents have to be all in the same folder. I also think that the links cannot be relative links. Is something like this possible in Alfresco, where the sub-documents reside in different folders or perhaps in a different site?
