Pick another one then :) - pretty much all other chars are safe except for
the surrounders, _ and % if you ignore languages and just consider DB
interfaces.

How about

	select =id, =title
	where (=id ...

to signal the 'link' ? OR how about just dropping it completely

	select id title
	from <dbms://localhost/rfid>
	where (id foo:id <urn:froefroe...
		..
	using foo ...

by simply insisting that any and all literals have a "" or '' , URI's
always have a <> around them and anything else must use a : separator
for the namepsace ?

Also think of the upside; do this right and you can instantly allow ANY
language/installation which has an ODBC, JDBC, ADO, whatever SQL interface
do semantic web queries with virtually no rework on the client side. AND
you get at least some instant buy in from the people currently in control
of data storage and the SQL bastion.
