regular expression for the XML datatype ‘duration’ incorrectly requires a decimal point in the seconds

What steps will reproduce the problem?

Parsing an RDF/XML value with datatype
http://www.w3.org/2001/XMLSchema#duration fails if the value contains
an integer seconds component.  My reading of the XML datatype spec is
that the ‘decimal’ does not require the decimal point.

What is the expected output? What do you see instead?

e.g. "PT12.0S" will parse, returning:

    ["PT12.0S", undefined, undefined, undefined, undefined, undefined, undefined, "12.0"]

While "PT12S" will not match, returning null.

What version of the product are you using? On what operating system?

Firefox 3.6.10, GNU/Linux.

Please provide any additional information below.

The fix is to add a '?' to the decimal portion of the seconds group in
the regexp.  The patch (to SVN head) is:

diff --git a/jquery.datatype.js b/jquery.datatype.js
index c30dae4..c871e01 100644
--- a/jquery.datatype.js
+++ b/jquery.datatype.js

   };

   $.typedValue.types['http://www.w3.org/2001/XMLSchema#duration'] = {
-    regex: 
/^([\-\+])?P(?:([0-9]+)Y)?(?:([0-9]+)M)?(?:([0-9]+)D)?(?:T(?:([0-9]+)H)?(?:([0-9
]+)M)?(?:([0-9]+(?:\.[0-9]+))?S)?)$/,
+    regex:

]+)M)?(?:([0-9]+(?:\.[0-9]+)?)?S)?)$/,
     /** @ignore */
     validate: function (v) {
       var m = this.regex.exec(v);
