This defines a mapping from the xsection to a new (gds) layer. It will use colors from the xsection and may have a name, however you can not use it in derived layers or DRC without giving it a name. Without name is therefore mostly handy for simple definitions. Type pdaGDSlayer documentation: The typical GDS type of thing, but including some coloring etc. In addition to the basic layer info, there is typical design rule definitions (min/max width, space etc) and derived layers (grow, size, not, xor, ...).

This defines a mapping from the xsection to a globally defined (gds) layer. Type pdaMCSgridToLayerItem documentation: The conversion from xsection to gdslayer is a key aspect. It is handled in this section where many map's can be defined.
Each mapping adds a possibly modified copy using the widening or lengthening of the data to the respective gdslayer.
