Thanks for applying the previous patch.  Attached below please find the
2nd patch that mainly covers the documentation changes, which include

  1. Some changes in org.texi to cover `#+XSLT'.
  2. An entry in Changes.org about the incompatible change.
  3. A small change in org-exp.el to include `#+XSLT' in
     org-get-current-options().

Hope I did not miss anything important.  Free feel to change the wording
or add anything that you'd like to add.

+*** Customizable variable changes for DocBook exporter
+
+To make it more flexible for users to provide DocBook exporter
+related commands, we start to use format-spec to format the
+commands in this release.  If you use DocBook exporter and use it
+to export Org files to PDF and/or FO format, the settings of the
+following two customizable variables need to be changed:
+
+1. =org-export-docbook-xslt-proc-command=
+2. =org-export-docbook-xsl-fo-proc-command=
+
+Instead of using =%s= in the format control string for all
+arguments, now we use /three/ different format spec characters:
+
+1. =%i=: input file argument
+2. =%o=: output file argument
+3. =%s=: XSLT stylesheet argument
+
+For example, if you set =org-export-docbook-xslt-proc-command= to
+
+: java com.icl.saxon.StyleSheet -o %s %s /path/to/docbook.xsl
+
+in the past, now you need to change it to
+
+: java com.icl.saxon.StyleSheet -o %o %i %s
+
+and set a new customizable variable called
+=org-export-docbook-xslt-stylesheet= to =/path/to/docbook.xsl=.
+
+Please check the documentation of these two variables for more
+details and other examples.
+
+Along with the introduction of variable
+=org-export-docbook-xslt-stylesheet=, we also added a new
+in-buffer setting called =#+XSLT:=.  You can use this setting to
+specify the XSLT stylesheet that you want to use on a per-file
+basis.  This setting overrides
+=org-export-docbook-xslt-stylesheet=.
