As you explore this topic - please keep this guiding structure in mind:

identify quirks or exceptions in specific reading systems (edited)
Identify gaps in documentation that need to be developed
Identify variations based of business verticals - how might you implement this standard differently as journal publisher vs a textbook publisher? A magazine vs scholarly? etc.
Use plain language. Use diagrams where they will help (and provide alt text). Tag your colleagues for assistance.
If you reference prior art, older development projects, or other materials, provide clarifying information including a basic definition and the importance to the best practice

When you are proposing language/contributions to best practice, please consider and respond to the following questions:
