I'm not sure from your description what you're trying to do (what
output you're trying to achieve). It's not clear whether you actually
want a parameter (declared with <xsl:param>, set on the call with
<xsl:with-param>) or you're using the term 'parameter' in a more
descriptive way. Perhaps you want two different templates for the two
different kinds of citation:

<!-- citations appearing in footnotes -->
<xsl:template match="db:footnote/db:citation">
  ...
</xsl:template>

<!-- other citations -->
<xsl:template match="db:citation">
  ...
</xsl:template>

These could both 'call' the same code where they needed the same
processing (whether by actually calling a template by name or by
applying templates to the <citation> element using a different mode).
For example:

<!-- citations appearing in footnotes -->
<xsl:template match="db:footnote/db:citation">
  <xsl:apply-templates select="." mode="citation" />
</xsl:template>

<!-- other citations -->
<xsl:template match="db:citation">
  <footnote>
    <xsl:apply-templates select="." mode="citation" />
  </footnote>
</xsl:template>

<xsl:template match="db:citation" mode="citation">
  ...
</xsl:template>

Cheers,

Jeni
