6.11.5 in the 1.2 spec says:
Attributes are intended as useful hints to the compiler. It is our intention that a particular implementation of OpenCL be free to ignore all attributes and the resulting executable binary will produce the same result. This does not preclude an implementation from making use of the additional information provided by attributes and performing optimizations or other transformations as it sees fit. In this case it is the programmer’s responsibility to guarantee that the information provided is in some sense correct.
My interpretation is it should be OK to ignore unknown attributes
