info on sablotron?

Hey, I was wondering if anyone here has used any recent version of
Sablotron and can tell me how it stacks up performance-wise, standard
compliancy-wise and if it supports most commonly supported extensions -
node-set(), multiple document outputs etc. 

The reason being that I noticed there's a new erlang module for working
with sablotron but from what I remember from quite a long time ago(more
than a year) the performance and compliancy were both awful. Anyone
correct me on that?
