The standard (or most usual) linear position of slot realisation in relation to the verb can be specified at the slot realisation level, by using a special attribute, in_order.
This attribute defines the preferred surface position of a slot realisation relative to the verb. It takes three possible values: pre, post, meaning that the slot realisation preferentially occurs in pre- or post-verbal position, and non-relevant when there is no preference. This attribute expresses preference depending on the verb or the language in question. Importantly, the order relative to self can also be fully constrained: it is then expressed at frame level using relative order constraints. This will be explained in the following.
