   * known limitations are notably that:

     1. plugin goal execution in a child is usually simply appended (at end): you can't try to insert in the middle of pre-existing inherited executions,

     2. append happens at plugin level first, then goal level, independently from phases.

        DomUtils.insertContentElement(root, "customElement", "custom value");

        String xmlOutput = DomUtils.toXml(doc);

        int versionIndex = xmlOutput.indexOf("<version>");
        int customElementIndex = xmlOutput.indexOf("<customElement>");

        // Custom element should be appended at the end

When the _access_ format is used, MinIO appends events as documents in an Elasticsearch index. For each event, a document with the event details, with the timestamp of document set to the event's timestamp is appended to an index. The ID of the documented is randomly generated by Elasticsearch. No documents are deleted or modified in this format.

      val fileBuilder = StringBuilder(key).append('.')
      val truncateTo = fileBuilder.length

        fileBuilder.append(i)
        cleanFiles += directory / fileBuilder.toString()
        fileBuilder.append(".tmp")
        dirtyFiles += directory / fileBuilder.toString()
        fileBuilder.setLength(truncateTo)
