34  * InputValue Pseudo-Tag
35  * Outputs a string for an input box from either an entity field or
36  * a request parameter. Decides which to use by checking to see if the entityattr exist and
37  * using the specified field if it does. If the Boolean object referred to by the tryentityattr
38  * attribute is false, always tries to use the request parameter and ignores the entity field.
