xlat is not an opcode; xlatb is. NASM syntax allows labels without a following colon, so a line containing simply "xlat" simply declares a label xlat. There is an optional warning you can turn on to warn on this case (-Worphan-labels). 

$ ./yasm -f bin -Worphan-labels test.asm
test.asm:1: warning: label alone on a line without a colon might be in error
