[XQuery] context for execution of imported functions

Hello,

I would have a question related to imported functions & variables: 
are they executed using the static context of the imported module or with the context of the importing module ?

[XQ-20041029]4.11. "....Each module has its own static context. A module import imports only functions and variable declarations; it does not import other objects from the imported modules, such as in-scope schema definitions or statically known namespaces. Module imports are not transitive-that is, importing a module provides access only to function and variable declarations contained directly in the imported module....." 

This makes clear that there is no access to indirectly imported functions, vars & type declarations. What about using them in a function body, or variable initializing expression?

Example: 
In order to use function a:A() in the main module is it enough to import the library "a"? or the library "b" has to be imported as well in the main module?


(:  library module a  :)
module namespace a="a";
import module b="b";
declare function a:A()
{
    'evaluated A()',
    b:B()
}

(:==================:)
(:  library module b :)
module namespace b="b";
declare function b:B()
{
   'evaluated B()'
}
(:==================:)


(:===main module====:)
import module a="a";
a:A();

Similar question for imported variables.


Best regards
