XML setAttribute() with US locale and ',' as a decimal separator

[boder]

I've set US locale with ',' (comma) as a decimal separator.
My code :

var xmlObject = new ActiveXObject("MSXML2.DOMDocument.3.0");
xmlObject.setProperty("SelectionLanguage", "XPath");
var datasetNode = xmlObject.createElement("dataset");
datasetNode.setAttribute("name", "test");
var recordNode = datasetNode.ownerDocument.createElement("test");
datasetNode.appendChild(recordNode);
recordNode.setAttribute("limit",5.5);

gives as result
recordNode.xml= <test limit="5,5"/>.
Why the attribute value has a ',' as a decimal separator??? I'm sure it should be a dot: <test limit="5.5"/>.

If you've "set US locale with ',' (comma) as a decimal separator."
and you are now getting the comma as a decimal seperator, what is the complaint?

If you want it as a period, then why don't you set period as the decimal seperator?

Hi!
It is a fragment of a wider application and users can use a different settings.
In all other settings it work properly, i have a result like <test limit="5.5"/>.
Only in US locale with',' it goes wrong.
