Code review comment for lp:~zorba-coders/zorba/bug1147563

Hi,

I fixed all the tests including the ones that were not using fn:nill and were using fn:data and instance of functions, this functions should work now correctly with nilled documents now. I am not sure if this 2 functions had errors of their own when handling nilled elements, if so they should be working now.

There is just one test failing though I think is a FOTs driver problem.
fn-nilled-49
The problem is that the query throws an error because a function in the main module is described like this

variable $queryID := xqxq:prepare-main-module
(
'
xquery version "1.0";
declare default element namespace "http://www.w3.org/XQueryTest/nillable";
        import schema default element namespace "http://www.w3.org/XQueryTest/nillable";
       /root/branch/date instance of element(*, date?)
'
, (), mapper:uri-mapper#2
);

thus throwing an error because of 2 references as default namespace. I am not sure why this happen or if this should work, but is the only example which imports the schema as a default element namespace together with a delcaration of an element namespace.

All the other tests are working.
