OK.. Two points.

Firstly, my appology.  I mistakenly believed sequence-size existed, since it's
previous- and next- counterparts do.  However, sequence-length aparently does.
(there is a reference to it in the ZQR, and it's also in the source code.)


Secondly, your problem stems from the fact that sequence-length is not a valid
variable name in Python.  you must use

<dtml-if "_['sequence-size'] > 1">

Annoying, yes... but that's the way somebody chose to go.  I don't know why,
but it's there.  In fact, if anyone could give me a good reason why it is this
way, I would be most appreciative.
