RE: Can a named template return a node list?

In XSLT 1.0, templates don't return anything, they write to the current
result tree (which might be the final result tree, or the contents of an RTF
in a variable). This means that if they produce nodes, the nodes are always
copies of nodes in the source, not references to original nodes.

This all changes with 2.0.
