The result of atomizing an empty node-sequence > is an empty sequence of strings. The confusion comes from this: <abc/> And a variable that selects <abc>: <xsl:variable name="abc" select="abc" as="xs:string?"/> And then use the test: $abc = '' The result is true. However, if <abc/> is not present, the result is false. So, what is the difference between the atomization process when the node <abc/> is present but empty, and when it's not there?
