  Hum, the idea is to link libexslt with it not libxslt.

   Hum, okay, so this seems to be a strong argument against 
this extension. 
   The alternate way would be to complete Mark Vakoc patch for
dynamic loading of shared libraries to get it working on Linux/Unix
and try to convert the new function to dlopening openssl and grabbing
just the functions needed for the task.
   That's a far bigger project but likely more useful as a whole.
