Question about help, hint and alert

Dear Working Group,

I am curious about the reason why there can be multiple alerts, helps 
and hints elements as children under a form controls.

Hints
-----
What is the expected rendering of several hints? Many implementations 
use tool tips but what would several tool tips look like in that case?

Helps
------
What is the expected rendering of several helps? Many implementations 
displays a help dialog but would one expect more than one dialog, should 
it pick one or collect the elements into one dialog?

Alerts
------
What is the expected rendering of several alerts? Some implementations 
displays the alerts as inline content which make the rendering of alert 
easy. Some implementations displays a modal dialog and here the question 
is the same as for help and alert.

The only reason for having multiple alerts, helps and hints I can think 
of is for localization in the UI using xml:lang but I thought that 
XForms expect an author to use instances for localization so I wondered 
if there is another reason. When creating a UI for XForms it seems to me 
that having 0 or 1 help, hint and alert element would be easier to both 
implement and use.

I have attached three testcases the working group can use for investigation.

Best regards,
David
