TITLE:		AN ANNOTATED TEST SUITE FOR THE X' THEORY GRAMMAR
AUTHOR:		Julie A. Van Dyke
COMMENTS:	(c) 1991 Julie A. Van Dyke

ABSTRACT:
This document provides examples of the range of sentences parsible by
the X' Theory grammar described in (Van Dyke, 1991).  It is an
illustration of the grammar's breadth of coverage and also displays
the details of the structures the grammar actually builds.  I have
included annotations with the parser's output in order to more
completely illustrate the interaction between the grammar and the
lexicon.  The grammar is crucially dependent on the specifications in
the lexical entries of each word and consequently, many structures
seen here can not be generated without particular lexical features to
license them.  It is my hope that the annotations found herein will
elucidate these features and thereby facilitate the creation of
additional lexical entries compatible with this grammar.

Within this suite there will be some instances where the grammar
generates several structures for a single sentence.  These typically
result from the inability of syntax alone to determine the correct
interpretation of a sentence.  Through these examples it will become
evident where non-syntactic components such as semantics or pragmatics
would come into play in a system using this grammar for natural
language understanding.

Finally, this suite will also serve as an excellent tool for
identifying areas in the grammar that could be improved or augmented.
Toward this end, I have included a final section illustrating some of
the structures the grammar does not yet handle.
