Aaron,
Nice work tracking down all this info on the Google Toolbar. I'm saving this post because I know I'll need it at some point in the future. Thanks! Mike
Field's with empty (or non-existent) title attributes *will* get taken over by GT, but if the field already has a non-blank title attribute, then it's safe. And if you're using plugin setting exclusively to define error messages, then title attributes don't matter at all because Validate will never look there (again, this relies on my line-swap fix[2] being applied) when it's looking for a field's error messages.
