In theory my guess would be that it should be possible to use non-browser 
parts, e.g. the wrappers around HttpXmlRequest.

Since JavaScript only needs the symbols that are actually used in executed 
code paths, not having DOM symbols shouldn't effect those other parts.

However, jQuery being designed to run across many browsers with different 
JavaScript APIs, will use the existance or absence of certain objects or 
functions as indicators which browser it is currently being executed in.

So it is likely necessary to examine how it usually determines that it is 
running inside the JavaScriptCore [1] version that is being used by QML and 
then provide those objects/functions/values in the context used by jQuery.

Cheers,
Kevin

[1] QML in Qt5 uses V8, but I think in Qt4 it is using then same engine which 
also powers QtScript and this is a copy/fork of some JavaScriptCore version if 
I remember correctly.
