Most organizations that regularly produce contracts or proposals should consider using XML, and in particular the Darwin Information Typing Architecture (DITA). Why? These documents use the same or similar sections over and over again, with enough variations — such as customer names and select clauses — to become the basis of expensive horror stories when mistakes are made as a result of search-and-replace or copy-and-paste errors. New technologies based on DITA can significantly reduce the risk of mistakes, while saving time and stress for staff as well.
