[xsl] xsl:number counting "cousins"

[Gustaf Liljegren <gustafl@xxxxxxxxxx>]

I have this source:

...
<colgroup>
  <col/>
  <col/>
  <col/>
</colgroup>
<colgroup>
  <col/>
</colgroup>
...

And this template:

<xsl:template match="col">
  <fo:table-column>
    <xsl:attribute name="column-number">
      <xsl:number count="col" from="ancestor::table//*"/>
    </xsl:attribute>
    ...
  </fo:table-column>
</xsl:template>

There's a fault here as you can see. The processor doesn't like what I put
in the 'from' attribute. It can only be children, not "cousins", like here.
Why this limitation? I think the above is pretty much straightforward. :-)

If I write like in the example in XSL (no 'from' attribute), I get problems
like this:

<fo:table-column column-number="1" .../>
<fo:table-column column-number="2" .../>
<fo:table-column column-number="3" .../>
<fo:table-column column-number="1" .../>

It starts over when it steps into the new group. What's the solution?
