Yes, though you might have an easier time getting your head around it if you look at it from the other direction. Rather than building a DTD out of blocks, you might think of it as replacing blocks in an existing structure, which has the effect of enabling or disabling other blocks. We used this approach when we did the Australian CALS suite of 27 DTDs - start with what is essentially a library of declarations and relationships and then use the DTDs to specify variations from that structure. As David M indicated, this is a bear to manage and requires parameter entities to be used throughout, though we overcame this by writing an application that generated normalised DTDs for applications and humans. -- Regards, Marcus Carr email: mrc@a... ___________________________________________________________________ Allette Systems (Australia) www: http://www.allette.com.au ___________________________________________________________________ "Everything should be made as simple as possible, but not simpler." - Einstein xml-dev: A list for W3C XML Developers.
