Missing DTD files

Hello,

My name is Rob and I work for Microsoft on their Live Search site. I  
was looking through the HTML and XHTML DTDs and found that I couldn’t  
access the links pointing to the XHTML 1.0 strict and transitional  
DTD. I found the XHTML strict and transitional DTD links in a couple  
place, but they were the same links. If there is a new location to  
these files, the links on the W3 site may need to be updated, or  
perhaps they were moved and some or all of the links haven’t been  
updated. I only looked through the HTML and XHTML DTDs though, so I’m  
not sure about the others.
