What the heck is this DocBook error?

I DocBookified the TWIG manual, but I can’t compile it due to some strange errors that don’t appear to be coming from the DTD…

jade -t tex -V tex-backend -d print.dsl /usr/share/sgml/xml.dcl AdminManual.db jade:AdminManual.db:3:57:E: URL not supported by this version jade:print.dsl:1:0:E: end of document in prolog jade:E: specification document does not have the DSSSL architecture as a base architecture make: *** [AdminManual.tex] Error 1
