Why doare people interestinterested in cohen macaulayCohen-Macaulay of codimension2codimension 2?

In deformation theory, CMCohen-Macaulay in codimension 2 is the first to be considered in higher order deformation. Does CMCohen-Macaulay in codim. 2 have some good property to work with? Does it somehow measure how singular a scheme is?

I am reading Hartshorne's deformation theory, and iI have difficulty to "see" why CCohen-MMacaulay in codim. 2 is a good object to work with.

Thank you very much

I am reading Hartshorne's deformation theory, and i have difficulty to "see" why C-M in codim 2 is a good object to work with.

Thank you very much
