"If you go through a Kendall and Kendall's Book it shows Context Level and Zero "0" Level as a different level DFD. According to Book by James A. Senn Both are same.
So, Whatever method you follow just mention the reference you have taken from that book.
From my point of view James A. Senn's book have clear and Correct approach toward DFD."

The level 1, called context DFD, shows the whole system in one process. Level 2 focuses more closely on one particular process in level 1, and level 3 focuses on a single process from level 2.
