Can we define module namespace for a file that exist at the same directory level as rewrite.xqy?

I have a file that exist at the same level as rewrite.xqy i.e. it doesn't exist inside a particular directory. When i am declaring a module namespace for it, I get the following error- 

<error:message>Cannot evaluate library module</error:message>
<error:format-string>XDMP-EVALLIBMOD: Cannot evaluate library module:

What is the logic behind this as when I remove module namespace it works just fine. These are the starting lines of my file- 

xquery version "1.0-ml"; 
module namespace adv = "http://***/***/adv"; 
import module namespace search = "http://marklogic.com/appservices/search" 
  at "/Marklogic/appservices/search/search.xqy";

xdmp:set-response-content-type("text/html; charset=utf-8"),

When you define a module namespace, your module is expected to be a library module with a collection of functions. You don't "run" a library module though. If you attempt to run this code, for example by pasting into QConsole, you will get the XDMP-EVALLIBMOD error.

A main module is expected to be executed as an XQuery program. Remove the module namespace module namespace adv = "http://***/***/adv";, and it will execute without error.

Or you can insert the code as a library module with the logic enclosed as the body of a function, import that module in a main module and call the function.

The error

<error:message>Cannot evaluate library module</error:message>
<error:format-string>XDMP-EVALLIBMOD: Cannot evaluate library module:

Means you are attempting to directly evaluate your code/module not import it. How are you getting this error ? For a xquery module, you cannot invoke it directly, you must import it in another file (usually the one you are invoking).

XQuery does not allow a single file to be both a main entry point and a module. When you say it 'works just fine' -- thats a good place to stop.
