<gpio> attributes
| id | ID | Specifies an unique identifier for this element. After defining an element with the id attribute, other elements can reference this element by using the idref attribute. Since the id attribute value is used by the code generator to generate field and method names, no spaces, periods or commas should be used. | optional |
| format | "binary" "decimal" "hex" "octal" | Specifies the numeric format base of data. For instance, if the protocol''s specification are in hexadecimal format, this attribute should be set to ""hex"". | optional |
| implementation | Name | Specifies the implementation class name. | optional |
| idref | IDREF | Specifies a reference to the element with the matching id attribute. The matching id attribute must be specified before the idref attribute can be used. | optional |
