I can use DocBook chunk.xsl successfully outside of oXygen which is why I ask this here. I have read the documentation but assume I am overlooking/misinterpreting something (probably obvious...). I set up a transform that under XSLT/XSL URL says: ${frameworks}/docbook/xsl/html/chunk.xsl I have left output alone. Running either Saxon 6.5.5 or xsltproc on valid DocBook 5 files, the transform produces completely empty files--not even declarations or anything, just foo.html without anything in them.
