Undeclared parameter that is not referenced in a for..in construct not flagged as an error.

Given:

declare function foo() {
    for $bar in $bar return <bar>{$bar}</bar>
};

The IDE does not flag $bar from the in $bar section as undeclared. The for $bar part is declaring $bar for the return <bar>{$bar}</bar> section, so those references to $bar should not be flagged with errors.
