The following variable should return a sequence of names that
only appear in EVERY section.
<xsl:variable name="ubiquitous-names"
select="distinct-values(sections/section/name
[not(contains(., 'new entry'))]
[every $s in sections/section
satisfies $s/name = .])" />
The context for sections/section is wrong. It needs to be
current()/sections/section.
So [every $s in sections/section satisfies $s/name = .]
doesn't seem to have any effect.
If X is an empty sequence, then "every $x in X satifies expr" is always true
(which sometimes surprises non-mathematicians).
