I think maybe the processor itself would be aware of whether it should be iterative or single. For example, Classification should know "I may get a set of results, but I only need one result to properly classify this resource". While, Hints should know "If I get a set of results, I should add it to each one." That is my thought anyway.

I think there is already a fix online in the PR. The problem was in Handler processing the xmls.

The problem here is that for some reason no result frames are being passed to the operations. Not so much an architectural issue, rather a bug.
