MarkLogic, cq and Namespaces

If you import an XQuery library in cq and declare the namespace, cq gets fussy if you then try to declare your own functions. I know there are clear reasons for this, but here's what I do so I can use my own functions during testing.

xquery version "1.0-ml";

import module namespace search = "http://marklogic.com/appservices/search" 
  at "/MarkLogic/appservices/search/search.xqy";

declare namespace my="http://www.my-web-site.com/xquery";

declare variable $options-title := 
<options xmlns="http://marklogic.com/appservices/search">  
  <searchable-expression>
    collection("abc123")//(div)
  </searchable-expression>
  <transform-results apply="snippet">
    <per-match-tokens>30</per-match-tokens>
    <max-matches>1</max-matches>
    <max-snippet-chars>200</max-snippet-chars>
    <preferred-elements/>
  </transform-results>
</options>;

declare function my:do-search()
{
  search:search("food", $options-title, (), 25)
};

my:do-search()
