This decimal fraction may be specified with either a comma or a full stop, as 
in 
"P0,5Y" or "P0.5Y".

Remember to accept both comma and a full stop.

Description:
------------
---
>From manual page: http://www.php.net/dateinterval.construct
---
The documentation says that "Each duration period is represented by an integer 
value followed by a period designator.", however, the ISO 8601 allows 
non-integer values for the last number 
(http://en.wikipedia.org/wiki/ISO_8601#Durations).
This is quite important if I want to parse XML data which contains 
millisecond-precision durations, as the seconds will surely not be integers.

Test script:
---------------
<?php 
   var_dump(new DateInterval('PT1.1S'));
?>

Expected result:
----------------
Should print out a valid DateInterval object, eg.:
object(DateInterval)#1 (8) {
  ["y"]=>
  int(0)
  ["m"]=>
  int(0)
  ["d"]=>
  int(0)
  ["h"]=>
  int(0)
  ["i"]=>
  int(0)
  ["s"]=>
  float(1.1)
  ["invert"]=>
  int(0)
  ["days"]=>
  bool(false)
}
It could also include a millisecond/microsecond/nanosecond field to accomodate 
additional precision. However, if the durations that are stored are still 
integers, it would be difficult to handle durations like "P0.5Y".

Actual result:
--------------
PHP Fatal error:  Uncaught exception 'Exception' with message 
'DateInterval::__construct(): Unknown or bad format (PT1.1S)' in -:1
Stack trace:
#0 -(1): DateInterval->__construct('PT1.1S')
#1 {main}
  thrown in - on line 1
