Since the same number gets used in two places (footnote mark in text 
mode, and footnote-list mode), I thought I'd create a function.  So I 
have:

  <xsl:function name="db:number-footnote" as="xs:string">
    <xsl:param name="footnote" as="element(db:footnote)"/>
    <xsl:choose>
      <xsl:when test="$chapters/db:chapter">
        <xsl:number level="any" count="$footnote" from="db:chapter"/>
      </xsl:when>
      <xsl:otherwise>
        <xsl:number level="any" count="$footnote"/>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:function>

  <xsl:template match="db:footnote" mode="footnote-list">
    <xsl:variable name="footnote-number" 
select="db:number-footnote(.)"/>
    <p id="fn{$footnote-number}">
      <a href="#fnm{$footnote-number}" class="footnote-anchor">
        <xsl:value-of select="$footnote-number"/>
      </a>
      <xsl:text>. &#xa0;</xsl:text>
      <xsl:apply-templates/>
    </p>
  </xsl:template>

However, I'm getting this error:

F XPath syntax error at char 0 in {$footnote}:
    Unexpected token in pattern, found "$"

Why?  And how can I fix it?
