xf:load with @resource pointing off to a bad link should generate a xforms-link-error and it currently doesn't. Can use the code out of nsXFormsMessageElement, probably, if we want to just do a simple test of the link first. Otherwise the code out of label should suffice. Should also generate an error in the JS console like label does, and generate the error during HandleAction. Since this is an action, we should probably test the link every time load fires to be consistent with what we are doing in message.

Asked for clarification on whether 4xx or 5xx messages should be displayed or not. Xforms 1.1 spec sure makes it sound like they shouldn't. Follow the thread here: http://lists.w3.org/Archives/Public/www-forms/2008Jan/0008.html
aaronr this seems to be blocked since 2008. Are you still working on this? Is this still a valid issue? I'll reset the assignee for now. Feel free to assign it again if I wrong.
The Mozilla XForms addon is no longer developed.
