Hi, how can I translate this Java[1] to XQuery according to [2]?   package com.vladsch.flexmark.samples;     import com.vladsch.flexmark.util.ast.Node;   import com.vladsch.flexmark.html.HtmlRenderer;   import com.vladsch.flexmark.parser.Parser;   import com.vladsch.flexmark.util.data.MutableDataSet;     public class BasicSample {       public static void main(String[] args) {           MutableDataSet options = new MutableDataSet();             // uncomment to set optional extensions           //options.set(Parser.EXTENSIONS, Arrays.asList(TablesExtension.create(), StrikethroughExtension.create()));             // uncomment to convert soft-breaks to hard breaks           //options.set(HtmlRenderer.SOFT_BREAK, "<br />\n");             Parser parser = Parser.builder(options).build();           HtmlRenderer renderer = HtmlRenderer.builder(options).build();             // You can re-use parser and renderer instances           Node document = parser.parse("This is *Sparta*");           String html = renderer.render(document);  // "<p>This is <em>Sparta</em></p>\n"           System.out.println(html);       }   } I only get so far as to:   declare namespace Node = "com.vladsch.flexmark.util.ast.Node";   declare namespace HtmlRenderer =" com.vladsch.flexmark.html.HtmlRenderer";   declare namespace Parser = "com.vladsch.flexmark.parser.Parser";   declare namespace MutableDataSet = "com.vladsch.flexmark.util.data.MutableDataSet";     declare option db:checkstrings 'false';     let $mds := MutableDataSet:new()   let $builder := Parser:builder($mds)   return $builder which results in   DataSet{dataSet={}} I found no documentation, on how to translate something as   Parser.builder(options).build() to XQuery. How do I express the method   build() of the instance   Parser.builder(options) I just created? Also, when I try the other way, by importing, for the following code   import module namespace Node = "java:com.vladsch.flexmark.util.ast.Node";   import module namespace HtmlRenderer = "java:com.vladsch.flexmark.html.HtmlRenderer";   import module namespace Parser = "java:com.vladsch.flexmark.parser.Parser";   import module namespace MutableDataSet = "java:com.vladsch.flexmark.util.data.MutableDataSet";     let $mds := MutableDataSet:new() I get:   [XQST0059] Could not instantiate com.vladsch.flexmark.util.ast.Node: java.lang.InstantiationException. Could it be, that it is only possible to call static properties via [1]? Am I right, that I need to write wrapper code in Java and then prepare results in a way, that I can retreive them from my own Java class? Thank you.
