XHTML Form - What Are the Values Submitted on Submit Button Fields

A "submit" button input field does not allow viewers to enter any input values directly. But if a form is submitted, "submit" button input fields will be submitted with values based on the following rules:

• If a "submit" button is not clicked, no value will be submitted for this submit button.
• If a "submit" button is clicked and no "name" attribute is specified, no value will be submitted for this submit button.
• If a "submit" button is clicked, "name" attribute is specified, and no "value" is specified, "Submit Query" will be submitted as the value.
• If a "submit" button is clicked, "name" attribute is specified, and "value" is specified, The specified value will be submitted as the value.
