I've been doing a bit more research on this... All DOM Level 1, 2 and
3 are very clear about the getAttribute() method (similar to
getAppStructureAttr), they all state that the return value is a
DOMString or an empty string if the attribute is not specified or
doesn't have a default (i.e., DTD) value.

Could you send us a pointer to the DOM 'undefined' concept?
