But it would deviate from that principle. It would change it from a
functional language to a procedural one, in which instructions have to
be executed in a fixed order.

XSLT 2.0 allows you to do this:

<xsl:for-each select="20 to 30">
  <xsl:value-of select="."/>
</xsl:for-each>

You can simulate this in 1.0 with

<xsl:for-each select="//node()[position() &lt;= 10]">
  <xsl:value-of select="position() + 20"/>
</xsl:for-each>
