XQuery in SQL 2012: .exist with multiple criteria

How do you code in XQuery (SQL 2012) to do an .exist with multiple criteria?

Given the below XML..

Declare @x xml = '
<row ParentID="45" ObjectID="0" Node="root.local.navigation[7]" itemKey="page" itemValue="Confirmation" itemType="string" />
<row ParentID="45" ObjectID="0" Node="root.local.navigation[7]" itemKey="visited" itemValue="false" itemType="bool" />'

Select allOpen in new window

These two criteria work fine when queried individually...

SELECT @x.exist('/row[@Node eq "root.local.navigation[7]"]')
SELECT @x.exist('/row[@itemValue eq "Confirmation"]')

Select allOpen in new window

But when I combine them below it returns errmsg 'XQuery [exist()]: The XQuery syntax 'union' is not supported.'

SELECT @x.exist('/row[@Node eq "root.local.navigation[7]"] | /row[@itemValue eq "Confirmation"]')

Select allOpen in new window

Thanks in advance.
