We have been also tested online help solution where quick help for inputting
complex medical fields was required

1) We added new AT field attribute called "help_link"

2) Help_link is a site path to Document object having the help text as body

3) If field has AT help_link attribute a help link (? in blue circle) is
rendered next to the field label. This requires overriding AT base files and
fields folder due to plone_skins limitations, making it unsuitable for
generic use.

4) If the user clicks blue ? a jquery pop-up DIV is displayed next to the
field label, showing the content of help_link Document, retrieved via AJAX.
Jquery pop up is automatically closed when the user navigates forward.

5) The help-pop has also [edit this] link which allows to edit the on-line
help in wiki style by users (by giving Modify portal content permission to
all Members via workflow), so that the users can help each other in common
problems

AT based approach is bad due to its ties into AT internals.  CSS rules +
Javascript based solution sounds more suitable. However, it could be still
reasonable to define the help link in the field definition, so that code
maintenance overhead doesn't raise too much because of decoupling of two
related items.
