I didn't say you can't, I was pointing out that the specification
doesn't require it. Various elements are specified as supporting the
load event, iFrame isn't one of them.
There are the following reasons why that is so:
1. iFrames are to some extent a replacement for FRAMESET elements,
which are specified as supporting the onload attribute
2. iFrames have their own window object and the window object has
historically supported the load event, so iFrames also generally
support the load event
Strictly, the onload listener should be on the iFrame's body element.
Putting it on the iFrame itself will be OK in most desktop browsers,
however given the rise of mobile browsers it may pay to follow the
standard as closely as is reasonable.

Who knows? One reason may be that the authors of the user agent
processing the markup did not program it to have that functionality.
