<!-- * This stylesheet makes a copy of a source tree, replacing all -->
<!-- * instances of the following with corresponding Xinclude instances -->
<!-- * in the result tree. -->
<!-- * -->
<!-- * <textobject><textdata fileref="foo.txt"> -->
<!-- * <imagedata format="linespecific" fileref="foo.txt"> -->
<!-- * <inlinegraphic format="linespecific" fileref="foo.txt"> -->
<!-- * -->
<!-- * Those become: -->
<!-- * -->
<!-- * <xi:include href="foo.txt" parse="text"/> -->
<!-- * -->
<!-- * It also works as expected with entityref in place of fileref, -->
<!-- * and copies over the value of the <textdata>“encoding” atrribute (if -->
<!-- * found). It is basically intended as an alternative to using the -->
<!-- * DocBook XSLT Java insertfile() extension. -->
