I've asked people to let me search their servers but everyone seems to
get really upset at that suggestion.
Are there any studies that show what practices are industrywide behind
the firewall? I have my suspicions on how it might break down, I'm
assuming the use of doctypes might depend on industry - for example
industries with heavy sgml backgrounds many doctypes, industries
without, not so much, as well as programming platform - microsoft, not
so many doctypes.

true, I forgot that, but then again
http://www.google.com/search?hl=en&lr=&c2coff=1&q=filetype%3Arss+%22xml%22&btnG=Search
there are many common extensions for xml files that could be searched
for, and that would probably be xml and, at least in the cases I'm
thinking of, possibly not have dtds.

IIRC svg files from adobe products tend to have a dtd declared, but
again IIRC only for pushing some entities in (don't really use any new
Adobe any more so I can't say what they look like nowadays)

 Many of those files look like

probably an indicator however that those files were xml on the server,
comes back to the subject of any studies of what is actually on the
server.

wasn't there a dive into xml article on xml.com in which the argument
was that xml had failed based on a crawl of results from the google
api of queries for xml documents. I didn't much care for that
article's conclusions, but maybe there was some good DTD info
somewhere in the dataset.
