Hi Michael. Thanks for your time and patience. Im working on a language called &quot;Fuzzy XQuery&quot; defined here in Simón Bolívar University(Caracas - Venezuela). Just like the xml:id attribute i want to create a new attribute called xml:truth which has to indicate the truth degree for each element that has this attribute after evaluating the query. And i need to define new kinds like &quot;declare fuzzy predicate young(-INF,0,,25,65)&quot; for example. I need to implement this on your source base because it&#39;s more efficient and robust.<div>
