Re: Fwd: XML Schema validation and https redirects

Hi Norm, Michael, thanks very much for these detailed responses.

Just a couple quick comments for now:

I included some rough stats in my initial message in the thread: 
https://lists.w3.org/Archives/Public/xmlschema-dev/2022Aug/0000.html

but it's hard to say what all the applications might be that show 
up as a generic UA like 'Java/*'

We are getting some useful data as comments on the blog post, 
https://www.w3.org/blog/2022/07/redirecting-to-https-on-www-w3-org/

I guess I was really wondering if the situation is closest to:

1) making this change will cause any use of XML Schema to break 
(sounds like that's not the case),

2) this may be a minor nuisance in the short term, but 
workarounds are readily available, or

3) this should only impact a handful of people using outdated 
software.

We are hoping our current 3-day https redirect experiment in 
progress will give us insight into which of these is the case.
