Your search looks for XML documents on the public web that have the word "doctype" and are in Google's index, which is not a good indicator of how much XML people are using that points to DTDs. A vast amount of the HTML out there, not to mention other formats, are created from XML behind firewalls. I think that content-oriented (as opposed to transaction-oriented--most call the dichotomy document-oriented vs. data-oriented) XML documents still favor DTDs because of the difficulties and complications of W3C Schemas, the presence of a potentially superior but less-adopted alternative (RELAX NG) that inspires a wait-and-see attitude, and the fact that they the documents' owners have publishing systems that aren't broken, so these owners don't see a need to fix them. Also, as near as I can tell, your search of 'filetype:xml "<?xml"' isn't looking for "<?xml" in documents, because Google does token searching, not string searching, so it's ignoring the "<?". Many of those files look like HTML files that happen to have extensions of "xml". So, that's not a good indicator of the number of XML files on the web.
