I'm pretty sure that XHR is used for screen-scraping beyond Wikipedia,
Since it'd fail any time the data is not well-formed XML, I'd actually expect such usage to be rare. It's not all that common to find "XHTML" on the web that happens to be well-formed XML.
Could some reasonably minimal, distinctive doctype be invented that would avoid the problem but not make the document look to humans and validators like it thinks it's some old version of XHTML?
Yes, but browsers would have to add explicit support for it.
Also, is this a wider problem? Are there any other tools besides browsers that might be magically allowing named entities for some doctypes only?
Sure; anything that actually goes and loads the DTD. -Boris
