Answer 1

There are several things here that aren't allowed in XQuery 1.0. The ones that stand out are:

declare  $dateTimeValue :=data($dateTime);

You can't declare local variables like that. You need let $v := expr return XXX.

return value (xs:dateTime(...);

The keyword return value is wrong and should be removed.

iterate $attribute over $chargeShareLines

I've no idea what the iterate expression does, but it's not XQuery. Looks like some variant of a for expression, but I don't know how it differs.

try {

requires XQuery 3.0/3.1, and the syntax is slightly different from yours.
