* ixmlElement_setAttribute
* Adds a new attribute. If an attribute with that name is already
* present in the element, its value is changed to be that of the value
* parameter. If not, a new attribute is inserted into the element.
*
* External function.
* Parameters:
* name: the name of the attribute to create or alter.
* value: value to set in string form
* Return Values:
* IXML_SUCCESS or failure code.
