The xapiwrapper has a subsection using the XDomainRequest object for CORS which suggests <=IE9. XDomainRequest was removed in IE10 and replaced with a standard CORS compatible XMLHttpRequest.
If IE10 is the minimum we can remove the XDomainRequest subsection and the Date.prototype.toISOString polyfill.
If support is needed for <=IE9 then it's currently broken here as ArrayBuffer and by extension Uint8Array objects don't exist below IE10.
