html5 overriding custom validation

[FireSBurnsmuP]

I have created a custom validator to handle the problem described in #158 as below:

$.formUtils.addValidator({
    name: 'group_one_required',
    validatorFunction: function (value, $el, config, language, $form) {
        if (value != '') {
            return true;
        }
        else {
            var $others = $($el.data('groupothers')),
            valid = false, i;
            for (i = 0; i < $others.length; i++) {
                var $this = $($others[i]);
                if ($this.val() != '') {
                valid = true;
            }
        }
        return valid;
        }
    },
    errorMessage: 'One of these values must be provided.',
    errorMessageKey: 'badGroupOneRequired'
});

And let's say I have the following inputs:

<input id="One" type="number" min="0" max="5"
    data-validation="group_one_required" data-groupothers="#Other">
<input id="Other" type="number" min="0" max="5"
    data-validation="group_one_required" data-groupothers="#One">

This is simplified, but will work just the same. If I initialize validator without HTML5 module enabled, with $.validate(); this validator functions. However, if I do use the HTML5 module ($.validate({modules: 'html5'});) my validatorFunction never gets called, as the call to $.validate({...}) changes

<input id="One" type="number" min="0" max="5"
    data-validation="group_one_required" data-groupothers="#Other">

to

<input id="One" type="number" min="0" max="5"
    data-validation="number" data-groupothers="#Other"
    data-validation-allowing="range[0;5]" data-validation-optional="true">

The expected functionality would be for the HTML5 module to append its rules to data-validation, effectively adding the HTML5 validation rules, instead of overwriting the attribute, effectively replacing any existing validation rules.

That is, the desired result would be

<input id="One" type="number" min="0" max="5"
    data-validation="group_one_required number" data-groupothers="#Other"
    data-validation-allowing="range[0;5]" data-validation-optional="true">

This would allow both validators to function. Could this be at least an option? I couldn't find anything on the site or README about it.

I have another issue with my custom validator, but that will be in its own issue.

Thanks as always for your time.
