GL_VERTEX_BINDING_OFFSET and GL_VERTEX_BINDING_STRIDE

I’m working through the state tables. As far as I progressed its actually straight forward, except for GL_VERTEX_BINDING_OFFSET and GL_VERTEX_BINDING_STRIDE. The later one doesn’t even default to the specified initial value of 16 but 0. I’m using nvidia propritary 325.15.

Which functions modify these values? I thought that glBindVertexBuffer could be a hit, but it only changes GL_VERTEX_ATTRIB_ARRAY_BUFFER_BINDING. Aren’t they redundant considering GL_VERTEX_ATTRIB_ARRAY_POINTER and especially GL_VERTEX_ATTRIB_ARRAY_STRIDE?
