^ Yes, perhaps - but this is configurable in the Options on the list page (i.e. "Attribute Value Protection") - I specifically only gave an answer to the question about subpage view/edit differences because there are quite a few variations of how the system may be set up and may behave that are not easy to summarise in a short answer.
For example display conditions do not allow different control (view/edit) of an attribute, and may also cause blank values in the list-page (if the options are set up like that), and I didn't want to over complicate the answer .... something that I have now failed at.
