As I'm somewhat reluctant to take NO for an answer, I have tried HTML entities for the left and right angled brackets as well. They will actually allow me to import the text, but the entity is displayed as text and not parsed into it's HTML equivalent. Maybe if the import routine in the Accordance Bible import code was modified so that instead of just looking for the angle brackets, it would look for allowable display modifiers encased in the angled brackets. This way, we could use angle brackets in User Bibles. Someone ought to suggest that.
Perhaps when Accordance allows the integration of PDF files we can take another look at the prospect of having the Emphasized Bible incorporated.
