RE: [xsl] Unexpected Results with format-number()

When I run your code on Saxon 8.9.0.4 I get:

Error on line 27 of file:/c:/temp/test.xsl:
  XTDE1310: format-number picture: Cannot have a grouping separator adjacent
to the decimal separator

After fixing that, there does seem to be a Saxon problem: a number that is
equal to zero after rounding to the required number of digits is displayed
as 0, not as 0.00.

The problem appears to be present in 8.9.0.4 but not in 8.9.0.3, so it
shouldn't be hard to track down.
