<p>
When the parsing of the whole sentence fails, fragmental parse results
are output.  In this case, the attribute "parse_status" will be
"fragmental parse".  Multiple &lt;cons&gt; elements are output
directly under &lt;sentence&gt;, and each of them represents a
fragmental parse result.

<p>
When parsing has failed, the "parse_status" attribute of
&lt;sentence&gt; represents the reason of the failure.  Neither
&lt;cons&gt; nor &lt;tok&gt; are output.
