This is clearly an error, since it is used in an example in 9.7, and a big one at that, since specializing this variable is apparently supposed to set the compute work group size at runtime.\r\n\r\nThe description should also clarify this process since it is not adequately described anywhere that I could find, including the SPIR-V spec (LocalSize cannot be specialized so I assume it should be interpreted by the implementation as the default value for WorkGroupSize?)."}}
