The fundamental publishing problem usually boils down to this:

• Editors don't want to be concerned with how their data is displayed. Crafting the words and ideas that constitute their content, the editorial creators would like to assume that, whatever design was agreed upon for the output, they don't need to worry about tags and fonts and so forth.
• Producers don't need to know about editorial data. They have designs implemented in the appropriate mark-up language. If editorial data needs any special adaptations, they don't want to be concerned with the details of the editorial copy, just how the formatting adaption should be implemented.
