using every inside a predicate

Hi

I am having trouble implementing a solution kindly offered on this list.

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 = .])" />

When tested on the XML below I get:

	<result>Kevin Bill Fred Ollie Harry</result>

Which is a list of distinct values, which I can get by:

	<xsl:variable name="ubiquitous-names"
			  select="distinct-values(sections/section/name
			  [not(contains(., 'new entry'))])" />

What I am after is:

	<result>Kevin Bill</result>

As these are the only names that appear in every section.

So  [every $s in sections/section satisfies $s/name = .] doesn't seem to
have any effect.

Can someone please point me in the right direction.

	<xsl:strip-space elements="*"/>

<xsl:template match="/">

		<xsl:variable name="ubiquitous-names"

select="distinct-values(sections/section/name
					  [not(contains(., 'new
entry'))]
					  [every $s in sections/section
satisfies $s/name = .])" />

		<result>
			<xsl:copy-of select="$ubiquitous-names" />
		</result>
</xsl:template>

Thanks.
