CALS DTD and its use (apology)

Folks sorry for the duplicate post. Email server took forever to respond so I thought I'd not hit send. So I sent it again.

It does not enforce specification requirements and pretty much allows the author to do dumb things (like put a couple of 'forewords' in the manual BEFORE the cover page). I haven't really looked at the NAVSEAC2 XML DTD or schema, but if they are done like the SGML DTD, I shudder.

When we did it, for inclusions, we went to the lowest element level and placed them there. Some people were not happy when tables and figures were no longer allowed just anywhere, but they've gotten used to it.

When they did their SGML to XML, they did inclusions (mainly tables, figures and foldouts) as an entity they tacked on nearly everywhere. So now if you have a requirement for a single paragraph of text, it may be repeatable because the group allows multiple tables, figures, or foldouts.
