When ICEfaces components with "required='true'" are rendered on browsers using HTML5 the "required" attribute is interpreted as the HTML5 "required" attribute. This results in the browser displaying a "Please fill out this field." tooltip (and aborting the submit) if you attempt a full Submit of the form without entering any values in the input component.

While it can be seen as being a handy client-side enforcement of the "required" policy, it actually causes a few unexpected issues in JSF:

* Aborts the entire submit, so any form components with validators (other than required=true) won't fire, and the user will only see the "Please fill out this field." tooltips for the required fields.
* Prevents the application from presenting any defined "requiredMessage"s of it's own.
* Results in the application having to localize the HTML5 error message in a manner completely different from the JSF component localizations.
* Looks different from the standard component messages in terms styling and location, etc.

This JIRA is to add a framework-level configuration to disable the built-in browser's HTML5 enforcement for "required=true", which should probably be the default as well (disabled).
