1. Extended SCCharts are merely syntactic sugar to Core SCCharts. Each Extended SCChart is expressable in Core SCChart syntax. 
2. Compilation of code from a Core SCChart is much simpler than compiling an extended SCChart. Because of the semantically equality, it's much easier to perform a model-to-model transformation than to compile an extended SCChart.
3. A basic block is a set of instructions, that can be executed as one piece. Instructions with more than one incoming or outgoing sequential control-flow-edges or tick edges trigger a break between basic blocks.
4. The ordering of a schedule is influenced by data-dependencies such as write-read, abs.write-rel.write and by the sequential control-flow.
