-    <para>When indexing, an &xml; Reader is invoked to split the input
-    files into suitable record &xml; pieces. Each record piece is then
-    transformed to an &xml; &dom; structure, which is essentially the
-    record model. Only &xslt; transformations can be applied during
-    index, search and retrieval. Consequently, output formats are
-    restricted to whatever &xslt; can deliver from the record &xml;
-    structure, be it other &xml; formats, HTML, or plain text. In case
-    you have <literal>libxslt1</literal> running with E&xslt; support,
-    you can use this functionality inside the &dom;
-    filter configuration &xslt; stylesheets.
