The compound "Wirtschaftsreform" consists of a frame-evoking element, "Reform", and a frame element for that same frame, "Wirtschafts". Accordingly, the compound has been split such that the two parts can be annotated separately.
Currently FrameNet does not contain a frame that would be appropriate for the word "Reform" of this sentence. So "Reform" has been assigned an Unknown frame. Still its core frame elements have been marked as Fe1 and Fe2.
