     * the DocBook Project (thanks Michael). It makes a listing tree of the

     * external text files referenced in the document, with each reference

     * replaced with corresponding Xinclude instance.

     * 

     *   <textobject><textdata fileref="foo.txt">

     *   <imagedata format="linespecific" fileref="foo.txt">

     *   <inlinegraphic format="linespecific" fileref="foo.txt">

     *

     * Those become in the result tree:

     *

     *   <listing type="textdata">

     *     <xi:include href="foo.txt" parse="text"/></listing>

     *   <listing type="imagedata">

     *     <xi:include href="foo.txt" parse="text"/></listing>

     *   <listing type="inlinegraphic">

     *     <xi:include href="foo.txt" parse="text"/></listing>

     *

     * It also works as expected with entityref in place of fileref,

     * and copies over the value of the <textdata> encoding attribute (if

     * found). It is basically intended as an alternative to using the

     * DocBook XSLT Java insertfile() extension.
