It will work if you give the parameters correctly, and if you honor database
opening requirements. (Like tagging write and running with the HOT parameter
if needed.) I have tested this with both global and catalog usertags.

I investigated this in case it was a bug, and got the following to
work just fine:

UserTag my_tag Order foo
UserTag my_tag Routine sub { return "foo=$_[0] tested" }

ActionMap  test_junk   <<EOR
sub {
    push @out,'testing: os28007';
    push @out, $Tag->data('inventory', 'sku', 'os28007' );
    push @out, $Tag->data('products', 'description', 'os28007' );
    push @out, $Tag->db_columns( { table => 'pricing' } );
    push @out, $Tag->my_tag( 'bar' );
    $Document->write(join "<BR>", @out);

% lynx -dump http://localhost/cgi-bin/construct/test_junk

   testing: os28007
   Disposable Brush Set
   q2 price_group sku q5 q10 q25 q100
   foo=bar tested

If there is a bug, we certainly won't find it without code exhibiting the

But, as usual, any time I start really looking at things I find room for
improvement. This time I made the creation of new keys in the database
a little more trouble-free with numeric fields, removing a redundant
part of Vend::Data::set_field. 8-)
