The filter regex for string I believe would allow this; a null value is valid. It is only testing for STRING ... not 'ISNULL' which is an entirely different test. Perhaps it COULD BE null.
This brings up a good point of providing a 'isNull' field for attribute or filter all depending on how you want to do this.
Proceed to create a node and you will observe that a "*" appears next to attributes that are required. However, the GUI and API allows for the Node to be created if the attribute is left as an empty string.
