Glazed Doors in Window and Door Schedules in Revit

I started out writing this blog post about the behaviour of subcategories in nested families.  On closer investigation, the weird behaviour I intended documenting was not as I had thought – still a bit strange but not quite worthy of a post all to itself.  So I have changed tack and turned it into a discussion about how to get a glazed door family to appear in both door and window schedules.  Many experienced Revit users should already know this, but for those who do not, read on.
