document that it won't work on IE 6/7 if user sets `document.domain`

[millermedeiros]

since it's an edge-case and the workaround is to use an empty HTML document for the iframe that syncs the document.domain of both sides I won't implement it.

Hi Miller,
Can you explain this with more detail? I might be suffering from the bug in my current project but don't fully understand the situation or the suggested workaround.
