Note
	An example on attribute algorithms can be found in the "Training" catalog ($CADENAS/training/training.cip) under \v11_news\value_ranges\value_ranges_with_condition\din_1771.prj.

Dependencies between variables are expressed using so-called attribute algorithms. In the example (see following figure), you can see that the variable NENN is represented by the product of variables H, B and L.

NENN = '$H.x$B.x$L.'
