The problems is that the syntax of a UDI doesn't fit into the syntax
of a MIME parameter (or an SGML attribute value...) because a UDI
might be arbitrarily long, and it cannot contain any whitespace (so
it can't be split across lines).
So these 200+ character UDI's for WAIS documents can't be
mailed around safely (even SGML has limits on the length of an
attribute value).
Heck, my WWW client (perhaps it's not the latest version, but still...)
can't even retrieve wais documents due to these problems.
