Number localization in XPath 'string()' function

["Sergei S. Ivanov" <iv...@aha.ru>]

Hello, all

It seems that when converting floating point numbers to strings, the
'string' function applies current locale settings. I.e. evaluating the
following rule in my environment (with Russian regional settings)
   <xsl:value-of select="string(number('10.21332'))"/>
I got:
  10,21332 <!-- note the comma instead of period! -->
Looking at org.apache.xalan.xpath.XNumber.str() function it proves that the
implementation uses the default DecimalFormat, dependent on the current
system locale.
After the careful examination of W3C XPath recommendation I tend to think
that XPath string() function behaves erroneously.

Looking forward for your comments,
