Your site is rejecting java user agents.

Hi,

My team develops java code, and until yesterday we were able to build  
our XSD components without any problems. Today we are getting an error  
stating that a W3C xsd is unreachable.

We have debugged the issue, and discovered that the following URL is  
blocking any requests with the word java in the user agent string:

http://www.w3.org/2001/03/XMLSchema.dtd

This effectively stops any java build tools from accessing this DTD.  
Can you please look into this and correct the issue.

Best regards,

Jason Butler.
