You may try '<dtml-with expr="tinytable">'.
If you do not use "expr", then "tinytable" is rendered (i.e. called)
and the result is probably a sequence which does not have a "title"
attribute.

You may find more information about non-transparent name lookup
in the "Name lookup" section of

But you probably know that already....
