bug: Amaya annotation client omits query string from annotation context URI

for example, if I use Amaya/5.3 to annotate a phrase on a web page with URL
http://www.petstore.com/catalog.jsp?item=fish
only the stuff before the '?' is sent to the annotation server, thusly:
<a:annotates r:resource="http://www.petstore.com/catalog.jsp" />
<a:context>http://www.petstore.com/catalog.jsp#xpointer(string-range(/html[1]/body[1]/p[10],"",150,15))</a:context>

This causes all annotations for every page of the catalog to "hang off" the 
initial default page, if it exists at all, and either "breaks" the 
xpointers or causes strange results.

Cheers, Gary
