Okay, so I asked too many questions or added too much context.  I'll make them clearer:

 

Where is the best documentation on this and other features in the editor? 

For example, is there more documentation available to licensed users that is not found publicly on your website?

 

I know that one need only specify the setting in one place (either the server code or the HTML tag), but I wanted to know how to change it from client-side code, if I wanted to, AND if it could be specified in a configuration file.  I am asking in order to gain a complete understanding and I expect to apply the lessons about this one setting to other features in your editor.

 

I would like to know the priorities of conflicting settings in multiple contexts if it can be easily specified.  This is not a pressing question, but a good one, nevertheless.

 

Thanks
