There is a demo of longdesc that Patrick Lauke wrote to go with his Firefox extension, last updated in 2008, which uses internal page links, and the extension as well as the browser-native implementations of iCab and Opera all handle the case of an internal reference just as they would an external one.

I don't know of any evidence that longdesc was intended to only work on external pages, despite some implementations failing if you don't do that.

So I think the HTML 4 spec was right, and we should re-affirm that, and file bugs against the software that doesn't implement it properly. (I have already done this for the Yandex browser...)
