Not to worry.  One of the requirements of the XQuery Update Facility is 
that it share the XML syntax that XQuery itself provides (called 
XQueryX).  In fact, I am personally on the hook to draft a proposal for the 
XQueryX enhancements to support the XQuery Update Facility syntax.

By the way, as Mike said, XUpdate is hardly a standard.  The spec itself is 
incredibly incomplete and has effectively been abandoned.  I am unaware of 
an update in the last few years.  While there are several claimed 
implementations, it is difficult to imagine that they are interoperable in 
any meaningful sense because of the large areas left unspecified that 
implementors would have to define for themselves.

Hope this helps,
