A question for clever chaps.
As you probably know, many TEI attributes have a declared value of
"anyURI", so they can point almost anywhere. Out of curiosity, what
techniques/tools do people recommend for the validation of said URIs? I
can find plenty of tools which will check that the syntax of the value
is correct, but what technique/tool would you recommend to find out
whether it is actually valid -- in the sense that starting from here
(where the document is) I can recover whatever it's pointing at?

Nicolas Larrousse and I postered at Rome)
