I use hack for support of client-size XSLT:

var defaultNS = document.documentElement.namespaceURI;
/**
 * Use the given object to override the given methods in its prototype
 * with namespace-aware equivalents
 */
function addNS(obj, methods) {
    var proto = obj.constructor.prototype;

    for (var methodName in methods) {
        (function() {
            var methodNS = proto[methodName + "NS"];

            if (methodNS) {
                proto[methodName] = function() {
                    var args = Array.prototype.slice.call(arguments, 0);
                    args.unshift(defaultNS);
                    return methodNS.apply(this, args);
                };
            }
        })();
    }
}

// Play nice with IE -- who doesn't need this hack in the first place
if (document.constructor) {
    // Override document methods that are used by jQuery
    addNS(document, {
        createElement: 1/*,
        getElementsByTagName: 1*/
    });

    // Override element methods that are used by jQuery
    /*addNS(document.createElement("div"), {
        getElementsByTagName: 1,
        getAttribute: 1,
        getAttributeNode: 1,
        removeAttribute: 1,
        setAttribute: 1
    });*/
}

And in funcion get error in line 5422:

"TypeError: Argument 1 of Window.getDefaultComputedStyle is not an object."

function actualDisplay( name, doc ) {
        var elem=jQuery( doc.createElement( name ) ).appendTo( doc.body );

        // getDefaultComputedStyle might be reliably used only on attached element
            display = window.getDefaultComputedStyle ?

                // Use of this method is a temporary fix (more like optmization) until something better comes along,
                // since it was removed from specification and supported only in FF
                window.getDefaultComputedStyle( elem[0] ).display : jQuery.css( elem[0], "display" );

        // We don't have any data stored on the element,
        // so use "detach" method as fast way to get rid of the element
        elem.detach();

        return display;
    }

As for me works:

function actualDisplay( name, doc ) {
        var origElem=doc.createElement( name );
        var elem = jQuery( origElem ).appendTo( doc.body ),

        // getDefaultComputedStyle might be reliably used only on attached element
            display = window.getDefaultComputedStyle ?

                // Use of this method is a temporary fix (more like optmization) until something better comes along,
                // since it was removed from specification and supported only in FF
                window.getDefaultComputedStyle( origElem ).display : jQuery.css( origElem, "display" );

        // We don't have any data stored on the element,
        // so use "detach" method as fast way to get rid of the element
        elem.detach();

        return display;
    }
