=head1 NAME

tv -- true temporary, non-session set/value tag

=head1 SYNOPSIS

[ts foo]The time is: [time fmt="%H:%M"][/ts]
[tv foo]
(Shows "The time is: 09:10")

[tn bar]The time tag is set as in: [time fmt='%H:%M'][/tn]
[tv bar]
(Shows "The time tag is set as in: [time fmt='%H:%M']")

=head1 DESCRIPTION

Interchange uses C<[tmp foo][/tmp]> and C<[tmpn bar][/tmpn]> to set
temporary scratch values. While this works OK in most cases, these
values have to be managed in the session, and also may overwrite values
which could be counted on by other pages (when set with C<[set ...]>) or by
manipulating $Scratch.

The above three tags replace this scheme with values that are based
in the C<$Vend::Interpolate::Tmp> space. These values are available
in embedded Perl with C<$Tmp>, so are usable in the same fashion as
C<$Scratch>. But they are truly temporary and will never be saved to
a session.
