[oXygen-user] Cannot find a matching 2-argument function named {org.dita.dost.util.ImgUtils}getWidth()

Hi I am trying to use oXygen to validate XSL that includes use of functions from "dost". The code runs in the DITA OT with no problems. Here is the error message: Description: Cannot find a matching 2-argument function named {org.dita.dost.util.ImgUtils}getWidth() Is there something I can do to my code or to my validation scenario to make oXygen validate this?
