Confused about the layer standards supplied with MEP 2008...

By default when i draw "Supply" duct it goes on "M-Duct-Std-Supp"...

I understand how the layer keys work and i COULD write from scratch a layer standard that matches the AIA/NCS standards but i should not have to do that... Right... ?? I am confused as to why the program insists that it IS using the AIA standards (AIA 256 Color)... Even the MEP guide book reads that AIA use something like "M-HVAC-DUCT-SUPPLY" AND NOT "M-Duct-Std-Supp"...

Am i missing something... ??

I have tried "MEP System - AIA 256 Color" and "MEP Object - AIA 256 Color" but neither of these seem to come with any layers the resemble AIA standard naming conventions... ??

Does any one have, or know where i can get a Layer Standard (with layer keys) that DOES use AIA standards...

Again does MEP come with that but i am just doing it wrong... ??
