If data selects anything, then it will select 7 child elements of <xml>, and
a sort key consisting of a sequence of 7 elements is unlikely to be useful.
Chances are you want

<xsl:for-each select="data">
  <xsl:sort select="." data-type="number"/>

Incidentally, element names beginning with "xml" are reserved for future
standardization, therefore best avoided.
