Good point, thanks. So the process is actually:

  document ---> PSVI ---> node tree ---> node tree ---> document
        (parsing) (building)   (transforming) (serialising)

                 +---------------------------+
                        XSLT processors

     +------------------------------------------------------+
                       XSLT applications


All XSLT processors need to govern the building and transforming
aspects; xsl:strip-space and xsl:preserve-space give control over the
building.

Standalone XSLT applications need to control the parsing and
serialising stages as well.
                        
Cheers,

Jeni
