Ah, got it after some head scratching. XSLT isn't my strong point to let me know if I'm doing something that's bad practise. Hope this helps someone else:

<xsl:variable name="allProjectsInCountry" select="umbraco.library:GetXmlNodeById($parentNodeOfProjects)/Project[@isDoc][contains(concat(',',
 countries, ','), concat(',', string($currentPage/@id), ','))]" />
  <xsl:variable name="allVideosInCountry" select="$allProjectsInCountry/FeaturedVideo" />
  
 
  <xsl:for-each select="$allVideosInCountry">
    <xsl:sort select="@id" order="descending" />

Hi Paul,

Just two things: You almost never need to explicitly cast anything in XSLT - so you can get rid of the string() function around $currentPage/@id inside the concat() function - that happens automatically, and not having to wrap that around helps the readability;

You say you want the latest FeaturedVideo, so I'd suggest you sort using either @createDate or @updateDate - they are XMLDates which are just text, but in a sortable format. You should not rely on the highest @id to be the latest node.
