Custom attribute vs data- * attribute

Question

I know that data-Attributes is part of HTML 5. It seems like a good choice to use to serialize some data in markup. So there are people using data-bind = "xxx". But can I just use bind = "xxx". It seems to violate the scheme, specifications, but practically it works in all browsers. So my question is: what is the practical reason (not in theory) as the performance, that I should not use the customs attribute in the same way as bind = "xxx". I know that the bind attribute is not a reserved attribute.

thanks
