Description

It was observed in a rule like:

((chunkType{-PARTOF(Enumeration),-PARTOF(ChunkCombineBlocker) -> Member} SPECIAL.ct=="-"? COMMA)* 
	    chunkType{-PARTOF(Enumeration) -> Member} SPECIAL.ct=="-"?{-PARTOF(chunkType)} COMMA?{-PARTOF(chunkType)}
	    @EnumIndicator{-PARTOF(Enumeration)} chunkType{-PARTOF(Enumeration),-PARTOF(ChunkCombineBlocker) -> Member}){-> Enum()};

Between EnumIndicator and the first left chunkType, several chunkType are skipped.
