Thanks for clarifying. I’d forgotten about that.

I suppose my question then is: since W3C is committed to maintaining
xml.xsd on the web, and it is pretty trivial to either (a) cache this
document so it isn’t fetched every time a MODS file is being verified
or (b) modify the xml.xsd to point to a local institution’s copy,
would it not be better to let this stand, rather than take on the task
of maintaining a compatible copy of xml.xsd?

But of course it is not me who will be maintaining this document, so I
don’t mean to raise a fuss.

best,
