           Summary: declare variable $input-context1 external;
           Product: XML Query Test Suite
           Version: 1.0
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XML Query Test Suite

Refering to a variable declaration of the form:

declare variable $x external;

the XQuery spec states in:

http://www.w3.org/TR/xquery/#id-variable-declarations

that:

"During query analysis, the type of $x is considered to be item()*. "

Thus XQTS tests which start:

declare variable $input-context external;

and use an expression such as $input-context/.... fail typechecking, since such
an expression requires node()*, not the more general item()*.

XQTS tests should therefore be changed to use, for example:

declare variable $input-context as node()* external;

Axes001-1 is an example of such a test.
