Subject: Re: [xri] Re: content negotiation for site-meta
I agree with your analysis. What makes me reconsider this is the lack of full overlap between /site-meta (text) and XRD. In my previous email you can see where I had to add another namespace to support <site-meta:scheme>. Since the text format will be required in any compliant implementation, maybe we should not support an XRD flavor of /site-meta.

I'm concerned that this approach will slow or stall deployment of
site-meta because it relies on HTTP features that are not
well-supported in current software. There are three problematic parts
of the architecture: the web servers, the intermediate caches, and the
clients. =)
I've done a bit of digging and written up my notes here:
