As has been said you need xsl:sequence or xsl:copy-of to get the whole
node not just the value of the node, but you could also make that
function a little more generic to create any attribute:

<xsl:function name="f:createAtt">
  <xsl:param name="name"/>
  <xsl:param name="value"/>
  <xsl:attribute name="{$name}" select="$value"/>
</xsl:function>

and then call it passing the the name value pair for the attribute,
and put the condition in a predicate:

<foo>
  <xsl:sequence select="f:createAtt('foo', 'bar')[current()/@value =
$something]"/>
