Function or template complexity

A function or template containing more than 50 XSLT elements is too complex to read and maintain. Split it into smaller, focused units.

Incorrect:

<xsl:template match="/">
  <!-- more than 50 xsl:* descendant elements -->
  <xsl:variable name="a" select="foo"/>
  <xsl:variable name="b" select="bar"/>
  <!-- ... many more elements ... -->
</xsl:template>

Correct:

<xsl:template match="/">
  <xsl:apply-templates select="header"/>
  <xsl:apply-templates select="body"/>
</xsl:template>

<xsl:template match="header">
  <!-- header logic -->
</xsl:template>

<xsl:template match="body">
  <!-- body logic -->
</xsl:template>
