I haven't been able to identify a bug here. If the function is:

  <xsl:function name="bib:footcite" as="xs:string">
    <xsl:param name="footciteable" as="element()"/>
      <xsl:number level="any" select="."
                  count="footnote|citation[not(ancestor::footnote)]"/>
  </xsl:function>

then Saxon complains rightly that there is no context item (note the
select=".").

If you change it to:

  <xsl:function name="bib:footcite" as="xs:string">
    <xsl:param name="footciteable" as="element()"/>
      <xsl:number level="any" select="$footciteable"
                  count="footnote|citation[not(ancestor::footnote)]"/>
  </xsl:function>

then it runs correctly.
