Is the purpose of this work to enable displays to get access to all 
their elements of a certain type? E.g. get access to all labels as you 
mentioned earlier?

If this is the case, would it be best to introduce a method like 
"getElementsOfType( typename )" to Dsp class? So developers would do 
something like this:

for label in Dsp.getElementsOfType('label'):
    # do something with the label element

Is that what you're looking for?
