Does your org own your domain name and trademark?
If not - make a fallback plan now!
I'm watching in horror as the W3C tries to retain control over its domain w3.org and the w3c trademark, which to date has been held on its behalf by MIT.
MIT's lawyers seem to me to have spotted an opportunity to make some money by gouging the not-for-profit standards body.
In case anyone was wondering why this matters:
xmlns="http://www.w3.org/1999/xhtml" is why.
(Update - TIL - Modern apps don’t actually fetch these references. So the next bit is wrong for most important cases)
If www.w3.org breaks - then _all_ those xml schema all over the web and in apps break too.
So it isn't a little not-for-profit corp matter.
It's an #infosec #ddos matter .
@steely_glint Not true. No XML parser actually fetches the namespace URIs.
Namespace URIs are strings. Their only purpose is to be a) uniqe and b) well-known. Whether there actually is anything at the URL in question is completely irrelevant. XML parsers do not care, and do not ever try to fetch anything from them. Nothing will break when whatever organization came up with a namespace changes their name or ceases to exist.
@tomalak Yes, you are right, I updated the post to correct this.
I am (as I said elsewhere in replies) 20 years out of date with XML. Back then we did read in public schemas, but that's now not done either.
Thanks for pointing out my error.
@steely_glint It's a common mistake to make, I've seen tons of people on Stack Overflow over the years making the same assumption, that's why my "hold up" reaction came so quickly. :)
Generally XML namespaces seem to confuse people even though they're quite straightforward.
