[Attempto] No DRSXML for "John likes Mary." in ACE 6.5?

[Joshua TAYLOR]

Hi all,

I'm updating some code to handle the new named proper names (among
other things) in the 6.5 release. For the simple sentence "John likes
Mary." I can get the DRS from the webclient:

[A]
predicate(A, like, named(John), named(Mary))-1/2

but can't generate DRSXML (after selecting the DRSXML checkbox, no
DRSXML is presented). Calling the webservice directly (via a Lisp
binding) shows that the drsxml element in the apeResult is empty,
although other formats (at least drs) still work:

CL-USER 27 > (invoke-ape-webservice :text "John likes Mary." :cdrs t :cdrsxml t)
"<?xml version=\"1.0\" encoding=\"UTF-8\"?>

<apeResult>
  <duration tokenizer=\"0.000\" parser=\"0.010\" refres=\"0.000\"/>
  <drs>drs([A], [predicate(A, like, named('John'), named('Mary'))-1/2])</drs>
  <drsxml></drsxml>
  <messages/>
</apeResult>

"

For other sentences, though, I can still get drsxml, e.g., for "John
should eat.":

CL-USER 28 > (invoke-ape-webservice :text "John should eat." :cdrs t :cdrsxml t)
"<?xml version=\"1.0\" encoding=\"UTF-8\"?>

<apeResult>
  <duration tokenizer=\"0.010\" parser=\"0.000\" refres=\"0.000\"/>
  <drs>drs([], [should(drs([A], [predicate(A, eat, named('John'))-1/3]))])</drs>
  <drsxml>&lt;?xml version=\"1.0\" encoding=\"UTF-8\"?&gt;

&lt;DRS domain=\"\"&gt;
  &lt;Recommendation&gt;
    &lt;DRS domain=\"A\"&gt;
      &lt;predicate ref=\"A\" verb=\"eat\" subj=\"named(John)\"
sentid=\"1\" tokid=\"3\"/&gt;
    &lt;/DRS&gt;
  &lt;/Recommendation&gt;
&lt;/DRS&gt;</drsxml>
  <messages/>
</apeResult>

"

Any thoughts? Thanks in advance, //JT
