What is the point of this ? 
still I have to do :
<map:match pattern="data/*">
  <map:select type="custom">
    <map:when test="goods">
      <map:generate type="goods"/>
    </map:when>
    <map:when test="contractors">
      <map:generate type="contractors"/>
    </map:when>
    <!-- 40 more -->
    <map:when test="stock">
      <map:generate type="stock"/>
    </map:when>
  </map:select>
  <map:serialize/>
</map:match>

even now without a custom selector I can do: 

<map:match pattern="data/*">
  <map:match patter="data/goods">
    <map:generate type="goods"/>
  </map:match>
  <map:match patter="data/contractors">
    <map:generate type="contractors"/>
  </map:match>
  <!-- 40 more -->
  <map:match patter="data/stock">
    <map:generate type="stock"/>
  </map:match>
  <map:serialize/>
</map:match>
but this is huge and grows every time I add some new functionality. With xsps 
I haven't touched the sitemap for months.
