You get only one attribute name/value, and no element information. My 
code simply needed to do something based on attributes in root element, 
before reading rest of the document. I'm not saying it's not possible to 
implement it, but it is not as straightforward as it could be.

My implementation look like this: I remember root element created in 
makeRootElement. I also have a flag called "rootAttributesReported". In 
startMakingElement and in finishMakingElement methods, if rootElement is 
set and rootAttributesReported is false, I pass root element to the code 
which checks its attributes. At this point, root element has attributes 
set. I hook into finishMakingElement method because my root element may 
be empty sometimes, thus startMakingElement would never be called ... it 
is called for elements inside root elements.

As I'm saying, it is possible to implement. I'm not even sure if method 
like "checkElementWithAttributes" would make sense in NodeFactory. But 
it sure would help me.
