Andreas, Ian,
thanks for the advice, it's been appreciated. I must admit to trying a number of different things recently, adopting a 'step-through' view and looking at the processing that occurs when FM starts. I've had mixed results, from FM crashing when opening the DTD (the catalog file and declaration file in the same app didn't want to talk) to pages of error messages. After changing the ref in the catalog file, the DTD opened nicely, no error messages at all AND with the catalog and declaration files in the same app. Thanks.
I hope I'm not stretching the friendship but I'm thinking of using the Pub Module (pm.dtd) as the basis for a Book. My situation is that I'll be using the descriptive dtd to write chapters (one FM file = one chapter) but then I need to incorporate them all into a FM book, together with prelim and post pages. I know it's not strictly in the intent of S1000D (in a CSDB and all) but I want to use S1000D as the structured basis so when it comes time to transfer into a CSDB it should be easier. Have either of you had experience in using an S1000D DTD to create the files (*.fm) which then get included into a book (*.book), and finally outputting to hard copy print? Advice greatly appreciated.
Cheers
Carl
