If not provided, cf_sebForm will supply a name attribute and make it unique per page. Optionally, you can specify this attribute yourself. if so, be careful to make it unique per page as server-side actions are tied to the form name.
The action of a cf_sebForm form is automatically set to the current page. If you change the value to something else, then cf_sebForm will not be able to act upon the form submit.
Whereas <form> defaults this value to "get", cf_sebForm provides a default value of "post". If, however, you set the value to "get", cf_sebForm will respond appropriately.
