Signature and transmission filters are applied with an order of precedence. This prevents potential filter conflicts, in which one filter might stipulate that you omit an item while another filter might stipulate that you keep an item.

In the XFDL language, options define the item characteristics. Options themselves may contain any number of array elements, which further define the characteristics. Options can contain simple character data, computes or computations, or array elements.
