According to the spec, when a sequence number contains more values than
there are formatting tokens, the last formatting token is used for the
excess values. Unfortunately, it is a little vague on which separator
token to use with the excess values.
It says that a '.' is to be used if no separator token exists, but does
this also apply to the case where the final formatting token is re-used
with excess sequence values?
Here is a quick test I did to try and see how different processors are
handling this:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:template match="a/b/c/d">
<xsl:number level="multiple" count="*" format="(1)"/>
</xsl:template>
</xsl:stylesheet>
If my input document is...
<?xml version="1.0"?>
<a><b><c><d/></c></b></a>
...then Saxon produces this:
(1(2(1(1)
...while Xalan produces this:
(1.2.1.1)
Both answers seem perfectly reasonable to me, given the lack of clarity
in the 1.0 spec.
Can anyone help me figure out which is (more) correct?
