I fear workflow variables cannot be accessed directly (they should probably).

However, there is a work around.

  The workflow tool provides a method "getInfoFor" (or similiar)
  that allows you to read workflow variables.
  Whether the "getInfoFor" is allowed depend of the workflow
  variable's "Info guard".
