OK..Let me see if I can explain it a bit clearer.
We basically have 2 scenarios where a rules engine needs to be implemented.
For our "new business" process I need an engine that examines application
type questions and returns a result for the policy. The result can be
either accept or reject the policy. The decision is made based upon a
collection of rules. For example if you have 3 speeding tickets in the
last month you will be declined. This engine has been created as I
explained before. The new engine is replacing COM components that have all
the rules hard coded in the form of "IF-THEN-ELSE" statements. The user
can now create the rules based on a schema that describes the message the
client will pass to the engine. The engine takes the rules entered by the
user and converts them to XQuery expressions. The engine than runs the
XQuery expressions against the XML being passed from the client to
determine the result for the policy (hold or accept). The second
scenario is we have another engine running on the mainframe that processes
policies when they renew on a yearly basis. This engine is basically a
COBOL program that processes a sequential input file and updates a VSAM
file with the results. This engine processes thousands of records every
night in a batch process. I would like to use the same client application
for building the rules as I mentioned in the first scenario. I would then
need a way to get a mainframe program that runs in a batch process to
somehow process the XQuery statements. I believe it would be too slow to
send mainframe records down to the server to run against the distributed
engine. I only have a short window for the mainframe batch process. Hope
this clarifies my situation. I've just started to examine the mainframe
process so I haven't really formulated any real solutions for the mainframe
side of the problem.

I am not sure from your question exactly what scenario you're talking
However it is worth noting that IBM this week acquired a mainframe data
integration firm called CrossAccess, which was pitched as filling out
its DB2 Information Integrator (II) strategy
DB2 II is where IBM plans to instantiate xQuery, and as such it looks as
if IBM is potentially moving in a helpful direction. Assuming xquery is
mapped to mainframe data sources accessed natively using CrossAccess
Until IBM delivers a native XML store for DB2 however, some of the
xQuery productization is on hold.
IBM was partnering with Nimble Technologies for xQuery support, but
Actuate acquired Nimble, so I am not sure of the status of that deal.
Hope that helps a little but I am not sure we understood your problem.
As SoftwareAG points out, Tamino already offers xQuery support on the

Not in the Yukon beta, but I am in the Whidbey alpha program.
The mainframe OS is IBM.
