Hi, I have a stylesheet customization layer that sets the keep.relative.image.uris parameter to zero. (therfore, they are resolved against xml:base) I verified that the customization layer works by using xsltproc (I have it on the Samba server that hosts my Windows files) on the xml source files and xsl customization layer (and yes, the xml catalog on the server points to docbook-xsl 1.70.1 as the current release). xsltproc --xinclude -o Engineering_Optimization.xhtml ~/.xml/alpha/xhtml.xsl Engineering_Optimization.xml When I transform with oXygen 7.2 and saxon 6.5.5 using the same customization layer (by placing file:/Z:/.xml/alpha/xhtml.xsl in the XSL url field), the file comes out ok, with the exception that the uris have not taken xml:base into account, so they don't point to the correct folder (and thus the images don't show in Firefox). I have tried setting the parameter keep.relative.image.uris to 0 inside oXygen, which doesn't work either. I created my transformation by cloning the DocBook HTML one and editing it to point to my xsl layer along with outputting to ${cfn}.xhtml. I am going to go download the regular Eclipse distribution instead of the Eclipse + Web Platform Tools distribution. If that fixes it, then I'll post to this thread again. -- http://chris.chiasson.name/
