Agreed... maybe.
But we come back to the central problem... namely that very few so-called learning objects have an inherent 'difficulty level' and even those that do can be used in different ways which means we have to associate properties like 'difficulty' with an educationalUsage rather than with the Resource itself.
I suppose we could define properties like 'intendedDifficulty' with definitions like 'the intended level of difficulty, as envisaged by the creator of the learning resource' but it seems to me that would be a significantly less useful property than something like 'difficulty' ??

Andy, here we hit upon rough shoals because limiting use of these education properties (DC and LOM) to resources “that HAVE BEEN USED as part of educational activities” eliminates 99% of all the resources of interest to the community to which these properties have been applied—millions of resource descriptions.

Subject: Functional requirements and the model
I was just taking a quick look at the functional requirements (http://dublincore.org/educationwiki/Functional_20Requirements).
As written, I think we have a problem with these in terms of the model (http://dublincore.org/educationwiki/Model).
We currently say things like:
Support the discovery of learning resources and activities targeted at particular levels of difficulty.
What I think we should be saying (in terms of the model) is:
Support the discovery of learning resources that have been used as part of educational activities targeted at particular levels of difficulty.
