Sounds reasonable.

Could you rephrase your question in terms of example markup
and client-server interactions?
Off the top of my head, this seems like a resonable usage:
See <A HREF="ftp://ds.internic.net/rfc/rfc822.txt"
URN="URN:EITF:rfc/822>The Format for Internet
Messages</a> for more info.
Clients that grok URNs can use the URN attribute, and other clients
can use the ftp: address.
This still strikes me as something of a hack, but it's a reasonable
hack in the near term.
