Okay, firstly, I notice dtml-tree doesn't support the standard
abbreviation:

<dtml-TAG "x"> -> <dtml-TAG expr="x">

As the following:

<dtml-tree "_.getitem('sequence-item',0)" branches="postingValues">

gives me:

Error Type: KeyError
Error Value: "_.getitem('sequence-item',0)"

nice...

Now the one that has me stumped :(

Why does the following:

<dtml-tree expr="_.getitem('sequence-item',0)" branches="postingValues"> 

Give me:
Error Type: NameError
Error Value: _

This is all in 2.1.6...

cheers,

Chris
