Which is not the same as select="foo//bar[1]"
but is the same as select="foo/descendant::bar[1]"/>

Whats the plain English version of this please.
Just what do the () do here?

<quote>NOTE: The meaning of a Predicate depends crucially on which axis
applies. For example, preceding::foo[1] returns the first foo element in
reverse document order, because the axis that applies to the [1] predicate
is the preceding axis; by contrast, (preceding::foo)[1] returns the first
foo element in document order, because the axis that applies to the [1]
predicate is the child axis.</quote>



Pudding and proof etc.



 <xsl:template match="/">   
 &nl; (1)<xsl:apply-templates select="foo//bar[1]"/>
  &nl; (2)<xsl:apply-templates select="(foo//bar)[1]"/>

&nl;(3)<xsl:apply-templates select="foo/descendant::bar[1]"/>
    </xsl:template>



    <xsl:template match="bar">
      <xsl:value-of select="name() "/>
    </xsl:template>
