14.<aui:validator name="url" />
Usage:Only URL is allowed in this field.

15.<aui:validator name="acceptFiles">
'jpeg, png'
</aui:validator>
Usage:Only allow files of the specified type.If all of these validation rules don't meet your needs, you can write custom rules, too.
This can be accomplished by using the "custom" rule name, custom "errorMessage"
attribute (more on this attribute further down), and a short Alloy Javascript function.
Your custom rule can do anything inside the curly braces as long as the return result
is a boolean. "val" is the value of the field (what the user typed in), "fieldNode" is
the node the validator is attached to, and ruleValue is what's inside the tag (in this
case, it's irrelevant because it is the script itself).


16--><aui:validator name="custom"
errorMessage="value-cannot-be-test">
function(val, fieldNode, ruleValue) { return (val !=
'test') }
</aui:validator>
