- original _property_ is `undefined` (scriptlet is called early enough) **OR**
- new _property_ written by `set.js` is `undefined` **OR**
- type of original _property_ is equal to type of new _property_
Additionally, original _property_ (if exist) must not have getter.
Value set by scriptlet can be overwritten by page script when:
- current _property_ was not set to `undefined` **AND**
- new _property_ is not `undefined` **AND**
- type of original _property_ is different than type of new _property_
