Hi David,
  I tried the following example with Saxon 8.1 ..

<?xml version="1.0"?>

<xsl:output method="text" />

<xsl:template match="/">
  <xsl:value-of select="string((2,3))" /> :
<xsl:value-of select="concat('a',('b','c'))" />


The output is -
2 : ab
(this is exactly as Mike explained)

In this example I believe I am asking a *pure XSLT
1.0* processor to work..

But I am using XSLT 2.0 sequence syntax in string and
concat functions .. Since sequence syntax is
unrecognized in XSLT 1.0 , should the above stylesheet
not give an error?

Or is some forward compatible behaviour going on.. 

I shall put my question more simply as ..
If <xsl:stylesheet version="1.0" is specified , and if
the stylesheet uses some XSLT 2.0/XPath 2.0 constructs
, then should the new constructs work - if I am using
a XSLT 2.0 processor? (as shown in example above)..
Ofcourse , the above stylesheet will give error with
XSLT 1.0 only processor (like Xalan-J 2.6.0) ..
