Numbering table footnotes XSLT 3.0 with xsl:number xsl-fo

Given this XML:

<reqSpares>
    <spareDescrGroup>
        <spareDescr>
            <name>Bulb</name>
            <footnoteRemarks>
              <footnoteRef internalRefId="ftn-0001"/>
              <footnoteRef internalRefId="ftn-0002"/>
            </footnoteRemarks>
        </spareDescr>                           
        <spareDescr>
              <embeddedSpareDescr>
                    <name>small bulb</name>
                    <footnoteRemarks>
                          <footnoteRef internalRefId="ftn-0002"/>
                    </footnoteRemarks>
              </embeddedSpareDescr>
        </spareDescr>
        <footnote id="ftn-0001">
            <para>Make sure the bulb works.</para>
        </footnote>
        <footnote id="ftn-0002">
             <para>Make sure that the new bulb is not cracked.</para>
        </footnote>
    <spareDescrGroup>
</reqSpares>

This will be a table with the footnote number in a row and the footnote number and footnote in the table footer.

Desired output (except the footnotes are in a table footer):

Actual output:

The footnotes are displaying correctly in the footer, but xsl:number is not working in <footnoteRef> (it's blank)

This also works in <footnote> but not <footnoteRef>:

<xsl:number count="footnote" from="reqSpares"/>

I did not think I needed to be in <footnote> to count <footnote> with xsl:number

XSLT:

<xsl:param name="footnote-count-pattern" static="yes" as="xs:string" select="'reqSpares/descendant::footnote'"/>

<xsl:template match="footnoteRemarks">
   <xsl:apply-templates/>
</xsl:template>

<xsl:template match="footnote">
    <fo:block font-size="75%">
        <xsl:number _count="{$footnote-count-pattern}" level="any"/>
        <xsl:apply-templates/>
    </fo:block>   
</xsl:template>

<xsl:template match="footnoteRef">
    <!-- only need footnote number here -->
    <fo:inline baseline-shift="super" font-size="75%">
      <xsl:number _count="{$footnote-count-pattern}" level="any"/>
      <xsl:text> </xsl:text>
    </fo:inline>
</xsl:template>

<xsl:template match="reqSpares">
      <fo:table>          
            <fo:table-column/>
            <fo:table-column/>
            <fo:table-header>
              <fo:table-row>
                <fo:table-cell>
                  <fo:block>Name</fo:block>
                </fo:table-cell>
                <fo:table-cell>
                  <fo:block>Remarks</fo:block>
                </fo:table-cell>
              </fo:table-row>
            </fo:table-header>
        <fo:table-footer>
          <fo:table-row>
            <fo:table-cell number-columns-spanned="2">
              <fo:block>
                <xsl:apply-templates select="descendant::footnote"/>
              </fo:block>
            </fo:table-cell>
          </fo:table-row>
        </fo:table-footer>
        <fo:table-body>           
          <xsl:apply-templates/>
        </fo:table-body>
    </fo:table>
</xsl:template>

<xsl:template match="spareDescr">
    <fo:table-row>
      <fo:table-cell>
          <fo:block>
            <xsl:apply-templates select="name"/>
          </fo:block>
      </fo:table-cell>
      <fo:table-cell>
        <fo:block>
            <xsl:apply-templates select="footnoteRemarks"/>
        </fo:block>
      </fo:table-cell>
    </fo:table-row>
</xsl:template>

Your pattern count=reqSpares/descendant::footnote is counting footnote elements, but the context item is a footnoteref, so there aren't any footnote elements to be counted. You need to navigate to the footnote element. Note that in XSLT 3.0 you can do this using xsl:number/@select - you no longer need to reset the context item using xsl:for-each.
