I teach law - and legislation and case names are simply wrong if not in italics. Students will be marked down for this error and we should always be modelling best practice to students. However, if I want to put up a content page in a module - or a module heading - which is the name of a case or a piece of legislation, I cannot do it in italics.
This means I am actually modelling to students what is wrong - rather than what is correct.
It would be great - and enhance teaching - if we could use italics for headings to Content pages and Modules. (Same issue exists in answers to quiz questions as well.)
