I appreciate > your discussion, but in this context I am not convinced its really needed. Maybe not.... My assumption is that we are using standard environments. The question I have, more theoretically stated, is the following: For real-world SGML processing, you need a SGML formatting system for converting SGML to different formats, and a build system, to control the invocation of the processors. The conversion of SGML to different formats involves "backend" systems. Different backend systems have different capabilities -- my specific issue here is that different backends have different image formats they know about. Either the build system should know about the image formats handled by the backend in question, and how to convert; or else the processor itself (taken as a whole, in this case, both Jade and JadeTeX, for instance) should know how to do conversations. In the latter case, either the processor backend system should know on it's own how to convert (Sebastian's suggestion), or else it's possible that the NOTATION system was meant for this purpose. Right now, the reality is that the build system needs to know about the backends' supported images. I am fine with that but just wanted to know what the SGML elite think about the issue. -- .....Adam Di Carlo....adam@xxxxxxxxxxxxxxxx<URL:http://www.onShore.com/> DSSSList info and archive: http://www.mulberrytech.com/dsssl/dssslist
