Mind adding your findings to the documentation?
http://docs.typo3.org/typo3cms/SkinningReference/UseCases/UseCase2RegisteringANewIconWithTheBackend/Index.html

There is a big orange button on the top-right: "Edit me on Github".

Just add your findings as nother use case. Then other can profit from your 
research.
