I have a following ZEN report:
Class ZENApp.Report Extends %ZEN.Report.reportPage
{
/// Class name of application this report belongs to.
Parameter APPLICATION = "ZENApp.SampleApp";
/// Specifies the default display mode used for this report if
/// the URL parameter, <var>$MODE</var>, is not present.
Parameter DEFAULTMODE As STRING = "xlsx";
/// This XML defines the logical contents of this report.
XData ReportDefinition [ XMLNamespace = "http://www.intersystems.com/zen/report/definition" ]
