[jQuery] Can you use jQuery within the MS JScript.VSA framework?

I working on a program which reads in scripts, and uses the MS
JScript.Vsa classes to execute those scripts. I would like to use
jQuery within those scripts, for its powerful XML-parsing
capabilities. However, when I include the contents of
jquery-1.2.1.js, and attempt to execute it using the
Microsoft.JScript.Vsa.VsaEngine, it throws a compilation error.
Has anyone worked with this configuration before? I can post details
about the error, but wanted to know if there was any more general
information / troubleshooting first.
Thanks for the help!
