this, *type=**xs:**unsignedByte*, is an attribute. I'm assuming "doc" above
is an instance of class Document, so you can get the element by using
doc.getElementsByTagName('complexType') or whatever it is you are talking
about for the element.

That will return an Element instance, and from there you can go haywire
adding attributes. The Element class has a method called
"setAttribute('string')".

You would do this right here:

    element=doc.createElement(name)
    <-- wave <--- element.setAttribute('string') <-- your argument here
    element.appendChild(doc.createTextNode(str(value)))
    parent.appendChild(element)

The node from your example has two attributes, and not one. I'm not sure how
important this is for you.

Anyway, that's my answer. I'm a newb though, and even more of a newb with
XML.
