Re: [docbook-apps] xml catalogs xerces, saxon, and olinking (target database is picked up as relative to docbook-xsl)
Solution: Switch to xsltproc and (on windows only) avoid all stylesheets that use the exslt node-set function. For the db4 to db5 (sans node-set) conversion, Bob Stayton might be persuaded to let you use his custom stylesheet from earlier in this thread. For the profile (sans node-set) step, use profiling/profile.xsl from the DocBook XSL distribution.
