External entities should be working in the next version. I'm not so sure
about parameter entities... if anyone has any experience with handling
them using expat (non-test version), I'm interested.

Yes, this is a general question; in XSLT, this could be done by
'extensions'.
Some namespaces can by designated as extension namespaces in the
stylesheet. 'Executing' an element or function from such a namespace
amounts to calling the corresponding function from an extension library.
Sablotron doesn't allow you to do this yet; one obstacle is how the
extension function would access the stylesheet and input trees.
Apparently, we'll have to implement a DOM interface for this purpose.
