My writer’s block for my XML-related standard went away.

I propose to classify XML namespaces into three distinct groups regarding “interaction” of elements (or attributes) of the same namespace.

Then we can transform between namespaces of the same precedences in such a way that in the case if elements interact, there remains only one namespace, thus not interacting elements of different namespaces.

I should write an exact specification for this idea, but the way is now open, I am past of my writer’s block.
