Done, Saxon 6.5.3 and MSXML 4 still work fine thanks.

I tried this but of course got problems with data typing.  I tried
having a stylesheet with version="2.0" import a stylesheet with
version="1.0" and vice versa, but both produced the same set of errors
(with Saxon 7.8).

There were only 2 types of error, they were:

  Required type of first argument of format-number() is number; supplied
value has type xs:string

  and

  Required type of first argument of concat() is xs:string; supplied
value has type xs:integer

So for example I changed:

<xsl:value-of
select="format-number(substring($figureDigits,1,2),'#0')"/>

To:

<xsl:value-of
select="format-number(xs:integer(substring($figureDigits,1,2)),'#0')"/>

And added these function definitions:

<exsltf:function name="xs:integer">
  <xsl:param name="x"/>
  <exsltf:result select="$x"/>
</exsltf:function>

<exsltf:function name="xs:string">
  <xsl:param name="x"/>
  <exsltf:result select="$x"/>
</exsltf:function>

....but msxml4 complains about the 'xs:' namespace.

Any ideas?
