JSON-encoding strings in XSLT 2.0

Hey,

is there some way in XSLT 2.0 to encode strings for use in JSON? In my
case, the stylesheet has to encode all text nodes in a XHTML fragment
which then gets passed to WYSIWYM editor constructor. Could this be
done as identity transform?

I had solved this problem when I used XSLT 1.0 on PHP by calling
json_encode() as extension function, but now I'm in the Java world.
