Technically, Rivet doesn't validate the character that immediately follows
<?, other than ensuring it is not <?=
The "xml" that immediately follows the opening sequence is being executed
as the command name. You don't even need to modify the source to Rivet
itself to define a proc in the global init script that was like this:
<?
proc xml {args} {
puts "<\?xml [join $args] \?\>"
}
?>
Then when Rivet encounters this sequence, it would execute the "xml" proc
and just output the tag as you intended.
<?xml version="1.0" encoding="UTF-8"?>
