What is the "generated" attribute seen in some HTML tag used for? -

i saw used in html label tag have feeling can used html tags. can kinda guess means. more curious what's benefit of using it. tried google reference couldn't find any, come experts. thanks.

example:

<label for="first_name" generated="true" class="error">this field required.</label> 

you use hook javascript and/or css.

for example...

css

label[generated=true] {    color: #ccc; } 

javascript

var labels = document.getelementsbytagname('label');  (var = 0, length = labels.length; < length; i++) {     if (labels[i].getattribute('generated') === 'true') {        // something.     } } 

it used on javascript generated elements, such label elements created jquery validation plugin.

you use jquery clean up generated elements with...

$('*[generated=true]').remove();
