Just for posterity (because I'm bound to forget...), to check I'm
doing it right if anyone cares to comment what I ended up doing was
something along the lines of:

<xsl:variable name="docs"  select="collection('../../working/xml/files.xml')"/>

<xsl:variable name="tables">
  <table element="placeName" att="type"/>
  <table element="persName" att="type"/>
  <!-- And many more etc -->
</xsl:variable>

<xsl:for-each select="$tables/tei:table">
  <xsl:variable name="table" select="."/>
  <xsl:variable name="pop"
  select="$docs//*[name()=$table/@element][@*[name()=$table/@att]]"/>
  <xsl:variable name="types"
  select="distinct-values($pop/@*[name()=$table/@att])"/>
  <table>
  <tr>
    <td>document</td>
    <xsl:variable name="types"
      select="distinct-values($pop/@*[name()=$table/@att])"/>
    <xsl:for-each select="$types">
      <td><xsl:value-of select="."/></td>
    </xsl:for-each>
  </tr>
  <xsl:for-each-group select="$pop"
    group-by="ancestor-or-self::tei:text">
    <tr>
      <td><xsl:value-of
        select="ancestor-or-self::tei:text//tei:date[1]/substring-before(@when,
'-')"/></td>
      <xsl:for-each select="$types">
        <td><xsl:value-of
          select="count(current-group()[@type=current()])"/></td>
      </xsl:for-each>
    </tr>
    </xsl:for-each-group>
</table>
  </xsl:for-each>
