I have something here but didn't work. Please advise

<xsl:when test="not(./*[name(.) = 'Shared']) |
(./Shared/text() ='N')">

This doesn't work because the union operator "|" works only on node sets, whereas the two expressions on either side of it here both return Booleans. You can't unify two Booleans.

I think you want

test="not(Shared) or Shared='N'"

...or (unabbreviated form of the same)...

test="not(child::Shared) or child::Shared='N'"

Translated into English, this reads "when there is no "Shared" element child or when a "Shared" element child has (string) value = 'N'.
