From looking at the sablotron binding from PHP 4, I dont see that it 
supported this. If I am incorrect, then if someone would kindly point 
out how this was done previously I would appreciate it.

There are a few ways to get node trees into a transformation though (and 
the methods appear similar to how it is done using the older extension).

- All libxml/libxslt I/O is now handled by PHP streams (which means 
users can register there own stream wrappers and call them anywhere a 
URI is valid). So a custom wrapper could return a tree built using DOM 
if it really wanted to.

- Call PHP functions directly from the templates. There are examples in 
the PHP manual for the registerPHPFunctions() method that explictly 
demonstrate PHP returning nodes to an in progress transformation.

I do believe some of the other processors like Saxon and Microsoft do 
support passing a nodeset in as a parameter.

I hope this answers your/their question.
