Using custom attributes makes your document invalid, you can use HTML5 data-* attributes and for getting/setting values using jQuery, you can use data method, for example if you have a data attribute called data-special you can get the value of it in this way:
var value = $("#my_tag").data("special");
and set/change the value in this way:
$("#my_tag").data("special", "value");

If you need to use it with jQuery then a better way to do it is to use data- attibutes.
Declaring a html tag will look like:
<div id="myDiv" data-url="asd/45.33/blah"></div>
Using data is as simple as:
var url = $('#myDiv').data('url')

Question about attr vs data.

USE attr() it is used for getting the value as well as for setting the attribute value.
$("#my_tag").attr("special_attribute",'asd/45.33/blah');

Yes it is possible. However it won't validate.

It will validate in HTML5 with the data attribute javascriptkit.com/dhtmltutors/customattributes.shtml
Yes you can. I think you should use an hidden field for this purpose:
<input type="hidden" id="my_tag" />
and then access it via jquery :
$("#my_tag").attr("value", "myvalue");
$("#my_tag").attr("value");

You can save value in html element as :
$("htmlelement").data("key","value");
in your case it would be :
$("#my_tag").data("special_attribute","asd/45.33/blah");

var html = "<p>HTML</p>";
$("#my_tag").attr("special_attribute", function() {
return html;
});
Now retrieve it with:
var s = $("#my_tag").attr("special_attribute");
alert(s)

why use function when you can simply assign a variable?

@AspiringAqib I know a lot of different people have told you already but at SO, we appreciate when there's a meaning behind the code you submit. If you can't answer the "why" question, perhaps it doesn't need to be there.
data-*attributes.
