/*================================================================
* ixmlElement_setAttributeNS
* Adds a new attribute. If an attribute with the same local name
* and namespace URI is already present on the element, its prefix
* is changed to be the prefix part of the qualifiedName, and its
* value is changed to be the value parameter. This value is a
* simple string.
* External function.
*
* Parameter:
* namespaceURI: the namespace of the attribute to create or alter.
* qualifiedName: the qualified name of the attribute to create or alter.
* value: the value to set in string form.
*
* Return Value:
* IXML_SUCCESS or failure
