Duplicate xsl:with-param name

A single xsl:call-template, xsl:apply-templates, xsl:apply-imports, or xsl:next-match supplies each parameter at most once. Two xsl:with-param children with matching @name is a static error — the processor cannot tell which value to bind — and rejects the stylesheet.

Incorrect:

<xsl:call-template name="render">
  <xsl:with-param name="colour" select="'red'"/>
  <xsl:with-param name="colour" select="'blue'"/>
</xsl:call-template>

Correct:

<xsl:call-template name="render">
  <xsl:with-param name="colour" select="'red'"/>
  <xsl:with-param name="weight" select="'bold'"/>
</xsl:call-template>
