+ |                              DESCRIPTION                                   |
+ if i want to emit the name attribute of the foo element that has the lowest bar 
+ attribute i would write something like:
+ 
+ <xsl:template match="...">
+   <xsl:apply-templates select="foo">
+     <xsl:sort select="@bar"/>
+   </xsl:apply-templates>
+ </xsl:template>
+ <xsl:template match="foo[position()=1]">
+   <xsl:value-of select="@name"/>
+ </xsl:template>
+ 
+ the problem with this is that i get the first element by the document order, 
+ not by the sort order
+ 
+ a more interesting variation of this example is this:
+ 
+ <xsl:template match="...">
+   <xsl:apply-templates select="foo">
+     <xsl:sort select="@bar"/>
+   </xsl:apply-templates>
+ </xsl:template>
+ <xsl:template match="foo[position()=1]">
+   <xsl:value-of select="position()"/>
+ </xsl:template>
+ 
+ here i emit the position() instead of the name attribute
+ in general it doesn't emit 1, which is quite strange, as the match pattern 
+ looks for position()=1
