[xsl] xsl:number question (XSLT 1.0)

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)"/>

If my input document is...

<?xml version="1.0"?>

...then Saxon produces this: (1(2(1(1)

...while Xalan produces this:

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?
