I know this is old news but I am replying anyway, regarding 
http://www.w3.org/2001/xml.xsd not responding...

The http://www.w3.org/2001/xml.xsd links do work but the W3C are taking 
"a number of defensive measures including utilizing a tarpit" due to 
"applications making excessive requests for DTD and other schemata".

See http://lists.w3.org/Archives/Public/site-comments/2011Apr/0026.html 
which references

For existing standards, I believe we need official change requests since 
nothing is currently broken.

FYI, I am not subscribed to this list.
