You're right: If you do not have a DTD or Schema, the Parser cannot 
identify Attributes of Type ID. What I did in my application [1] is that I 
can select Id attributes in elements from XML Signature space, because even 
without Schema, you know that an "Id" Attribute in an Element from 
Signature namespace _is_ of type ID, so you can catch them. If the user 
tries to identify IDs from other elements, my software does not catch them 
without tricks, but if the user helps me (uses my 
registerElementById(Element element, String idValue)), the parser can even 
find these elements.
