<pre><code><span class="codeComment">//Default InsVal function

// Insertion is by default, always valid.
// If any RI constraints are violated,
// DB will return errors when the actual insert is performed
// which occurs after InsValidate returns.
// If there are certain business rule constraints you wish to enforce, put them in
// your own InsValidate functor.
// You can also specialize this template if you wish to have different default behavior
// for your data class.</span>
