... HPSG grammar can handle word
order constraints in a computational pars-
ing system, without invoking an additional
layer of representation for word order,
such as Reape’s Word O rder Domain. The
key ... crucial for this WOC-incorporated gram-

stated in WOC are passed on and enforced in its
projection. I attempt to formalise...

In this paper we presented a technique for extract-

Furthermore, it seems we have captured order-
