situation where the books included this charge, but the books were already

closed for the financial period (e.g., the books had already been audited).

Changing the payee was a method for documenting the expense.  You might use

it like this:

    2011/05/28 My Bad Billing Hosting - NEVER CHARGED

        Liabilities:Credit Card:Visa            $-100.00

        Expenses:Conservancy:Hosting             $100.00

    2012/01/01 My Bad Billing Hosting - REVERSAL - NEVER CHARGED

        Liabilities:Credit Card:Visa             $100.00

        Expenses:Conservancy:Hosting            $-100.00

However, going forward, you'd likely never enter anything the ledger

**until** you had real proof via an Invoice, Receipt or Statement that showed

the Expense did/should occur.  This use of `NEVER CHARGED` in the payee is

thus deprecated.

#### Income Account Documentation

Each `Income:` account must have the following tags:

* One of: [`Invoice:`](#invoice-tag),

  [`PurchaseOrder:`](#purchase-order-tag),

  [`Contract`](#contract-tag).  Exceptions to this requirement are as follows:

     + the income generated from the transaction is less than $800, or

     + the `IncomeType` is `RBI` and the income is for a defined, public

       program (such as conference registration)

* An [`Entity:`](#entity-tag) tag, *iff.* the Income for the transaction is

  for more than $800.

* An [`IncomeType:`](#incometype-tag) tag.

* A [`Program:`](#program-tag) tag.
