With jQuery 1.1.3.1, I was sending an XML document as the data

parameter (along with processData set to false) to several $.ajax()

PUT and POST calls. However, I'm getting an exception with 1.1.4

inside jQuery.extend at line 358. I changed that line to not try to

iterate over prop if it is an XML document, however I'm not aware of

any other side-effects:

if (((prop = arguments[a]) != null) && (prop.nodeType !== 9)) 

According to the W3C,

XmlHttpRequest.send should support documents:
