Because Linear_cell_complex is a generic class, having an item class as 
template argument, and you can use any attribute associated with 0-cells.

This item class must be a model of the LinearCellComplexItems concept, 
which requires to  that 0-attributes are enabled, and associated with a 
type of attribute being a model of the CellAttributeWithPoint concept.

When you define your own model of the LinearCellComplexItems concept, 
you need to satisfy this requirement.
