AFAIK, there simply isn't any way to do this without adding "tep" to the dictionary. If you're curious for the reasons for this, see http://social.msdn.microsoft.com/forums/en-US/vstscode/thread/d63b9cad-1133-403c-bdb4-526263d4b55d.
If adding "tep" to the dictionary isn't acceptable, the only other feasible option would be to suppress the violations individually (assuming that you want to keep the rule enabled).
