XSLT Step Throwing Errors applying stylesheet

Unknown

We are using XSLT transformation in one of our Flows. XSLT step is returning below error.

But we verified the XSLT file and its working fine in our local XSLT processor.

I have attached XSLT file and XML input file

Name: [b][BusinessRule] XSLT stylesheet format is invalid[/b]
Exception Message: [b][BusinessRule] XSLT stylesheet format is invalid

Input Values:
-- No Data --

Exception Stack Trace: DecisionsFramework.BusinessRuleException: [BusinessRule] XSLT stylesheet format is invalid at DecisionsFramework.Design.Flow.CoreSteps.XML.ApplyXSLTStylesheetStep.ApplyXslt(TextReader xmlDocReader, TextReader xsltReader) at DecisionsFramework.Design.Flow.CoreSteps.XML.ApplyXSLTStylesheetStep.Run(StepStartData data) at DecisionsFramework.Design.Flow.FlowStep.RunStepInternal(String flowTrackingID, String stepTrackingID, KeyValuePairDataStructure[] stepRunDataValues, AbstractFlowTrackingData trackingData) at DecisionsFramework.Design.Flow.FlowStep.Start(String flowTrackingID, String stepTrackingID, FlowStateData data, AbstractFlowTrackingData trackingData, RunningStepData currentStepData)[/b]

In older versions of the Microsoft .Net Framework a bug exists that causes errors on processing long or complex XSL Stylesheets. Some details about the issue can be found here: [url=https://stackoverflow.com/questions/16091351/exception-stylesheet-is-too-complex-when-loading-large-xslt-in-net-4-5/16341246]https://stackoverflow.com/questions/16091351/exception-stylesheet-is-too-complex-when-loading-large-xslt-in-net-4-5/16341246[/url]

In order to resolve the issue, a change is required to the DecisionsServiceHost.exe.config file located at C:Program FilesDecisionsDecisions Services Manager to turn off complexity limitation.

The attached snippet must be added after the configuration tag.

Once the change is made, a restart of the Service Host Manager service is required.

Ive also attached the full DecisionsServiceHost.exe.config file with the added snippet for reference.
