  18 <!-- * This stylesheet makes a copy of a source tree, replacing all -->
  19 <!-- * instances of the following with corresponding Xinclude instances -->
  20 <!-- * in the result tree. -->
  21 <!-- * -->
  22 <!-- *   <textobject><textdata fileref="foo.txt"> -->
  23 <!-- *   <imagedata format="linespecific" fileref="foo.txt"> -->
  24 <!-- *   <inlinegraphic format="linespecific" fileref="foo.txt"> -->
  25 <!-- * -->
  26 <!-- * Those become: -->
  27 <!-- * -->
  28 <!-- *   <xi:include href="foo.txt" parse="text"/> -->
  29 <!-- * -->
  30 <!-- * It also works as expected with entityref in place of fileref, -->
  31 <!-- * and copies over the value of the <textdata>“encoding” atrribute (if -->
  32 <!-- * found). It is basically intended as an alternative to using the -->
  33 <!-- * DocBook XSLT Java insertfile() extension. -->
