Hi whatwg,
I've added a proposal to the wiki
<http://wiki.whatwg.org/wiki/AllowSeamless> about letting a document
indicate that it is willing to be displayed seamlessly with a
cross-origin parent. This proposal is a refinement of the approach
previously discussed in this thread:
<http://old.nabble.com/crossorigin-property-on-iframe-td33677754.html>.
Let me know if you have any feedback.
I have a strong feeling that per-origin control should be made easy for
authors. I must admit that I am not familiar with the mechanisms you
name, Frame-Options and ancestor-origins - and both are quite hard to
google for. From what I found I assume both are about HTTP headers.
If they are solutions that can be used easily with server-side languages
such as PHP, I think we can live with it. But anyway it is a
complication; I'd personnally prefer something like
allowseemles="example.org, *.example.org, shop.otherdomain.com"
Or maybe space separated, and separate inherit-style with comma:
allowseemles="example.org *.example.org shop.otherdomain.com, inherit-style"
(Regardless of whether it is in the HTML element or in a META element.)
