Rules

The rule schemata that will be defined in this paper are instantiations of the following general schema:

\enumsentence{ $ M \rightarrow L^* ~~ H ~~ R^* $\ \hfill{\sc combination-schema}}

This rule states that a mother node dominates a head daughter H, with an arbitrary number of daughters to the left of H and an arbitrary number of daughters to the right of H.3

The following constraints are attached to this rule schema:

\enumsentence{ \begin{description} \item[Head-feature principle:] The {\sc head}... ...e, whereas the elements right of the head have {\em right}. \end{description}}

Note that the first three constraints are standard in HPSG. The fourth constraint will be motivated in section 3.3.

We consider the rules that will be defined in the remainder of this article as (more specific) sub-types of (8) and (9).
