The hardest part is going to be *finding* the SDATA references to
process.  Since Jade hasn't implemented (query) yet, you have to
iterate over the content of every mixed-content element looking for
them.  See the (process-text) routine in
<URL:http://www.oreilly.com/people/staff/crism/dsssl/mifout.dsl> for
an example of doing this.  You can leave the entity as SDATA, and then
do

(make formatting-instruction
      data: (node-property 'system-data
			   this-node))

The formatting-instruction will pass the SDATA system data exactly as
entered, without turning less-thans and quotes into entity references.
