CLASSITEM and logical EXPRESSION based on more attributes?

[Carsten Dewey]

Dear list,

I would like to define a CLASS using a logical expression based on different
attributes inside EXPRESSION:

EXPRESSION ("[AR_Auto]"="N" and "[AR_Pedestrians]"="Y" and
"[AR_Trucks]"="N")

What about the CLASSITEM in this case? 
Define the LAYER just without?

Thank you & kind regards
