If a webpage was served AS XHTML, did frames ever work? So far as I can tell, what's supposed to open up in one of the "panes" is opening up in a new window instead. Just experimenting with something.
See for instance http://www.w3.org/QA/2002/04/valid-dtd-list.html for DOCTYPES

For details on <frameset> see for instance http://www.w3.org/TR/html4/sgml/framesetdtd.html
See for example http://www.htmlhelp.com/reference/html40/frames/frameset.html
You set the initial source of the individual <frame>s and name each so links can use name as target.
You're missing the point of what I was asking. I'm asking if a frames page, using the XHTML 1.0 Frameset doctype and with a file extension of .xhtml, .xht, or .xml would work properly. So far as I can tell, it doesn't.
