Accessing Request & System Variables from XSLT in API Gateway

Product : webMethods API Gateway 10.15 On Premise

I am trying to access the system variables such as Correlation ID & HTTP Headers in XSLT (Request Transformation) . I could not find any documents or topics around how can access it from XSLT. If some one is aware could you please share the syntax & list of available variables

Thanks

hi @mvsuhas ,
I doubt we can access the variable framework inside the xslt.
