What is the semantics?

pdfTeX generates 1.x and an image has version 1.y:
x := \pdfoptionpdfversion
z := \pdfoptionpdfversionerrorlevel

x >= y
  no problems

y > x
  ??
  * Abort with error message / continuing with warning
    depending on z.
  * Accepting some images with versions smaller 1.z or 1.(x+z)
    with warning, aborting otherwise.

What happens, if there will be PDF 2.? some day?
