Plan document 401(h) accoounts

Anyone know of plan document software that provides for 401(h) accounts in a money purchase plan?  I'm striking out everyplace I've checked.  Thanks!

Interesting question.  Long ago, I amended a few DB plans to add 401(h) accounts.  I simply used the regulations as my guide to basically recite the requirements for a 401(h) account, then made the language consistent with the plan document.  Other than the fact that I didn't have any sample amendments to work from, I don't think it was all that difficult. 

I haven't checked recently but the IRS used to publish a checklist that had to be completed when submitting a determination letter request application that included a 401(h) account.  Here is an older document that includes the checklist along with a more detailed discussion of the other issues involved:
