Expecting a null returned from XML.value() in SQL, but getting 0

[dhisme]

I'm attempting to read a specific value from an xml parameter passed into a stored procedure. A rough example of my code so far is below.\[code\]SET @SearchFilter = '<?xml version="1.0"?> <KeywordSearch xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <SelfEmployed xsi:nil="true" /> </KeywordSearch>'SET @SelfEmployed = @SearchFilter.query('/KeywordSearch/SelfEmployed[1]').value('/', 'bit')SELECT @SelfEmployed\[/code\]The issue I'm having is that, although the above correctly returns when the element contains a true or false value, where the element contains no value, and thus I'm expecting null, it returns false. Is there a way to correctly obtain the datatype as a nullable bit value?
