That is concerning for me when configuring option 43 in general.  There is 
another alternative using the conditional if statement on the vendor class 

subnet a.b.c.d netmask {
  if option vendor-class-identifier = "Cisco AP c1200" {
    option vendor-class-identifier "Cisco AP c1200";
    option vendor-encapsulated-options f1:02:ac:11:8e:36;
  elsif option vendor-class-identifier = "Cisco AP c1240" {
    option vendor-class-identifier "Cisco AP c1240";
    option vendor-encapsulated-options f1:02:ac:11:8e:36;
  .. etc.

Would that work better for scoping?
