This is usually done using a grouping idiom (see jeni's pages for xslt1
or for-each-group in xslt2)

xsl:sort changes the order in which teh results of processing nodes are
added to the result tree, it doesn't change the input tree, so it does
not change the preceding-sibling axis of the nodes.

> Would xsl:sort only sort the first record (doing nothing)?
yes.

              <xsl:for-each select="Record[1]">
              <xsl:apply-templates select="." />
    </xsl:for-each>

That is equivalent to 
<xsl:apply-templates select="Record[1]"/>
