For the SOAP interface, I'd look at using XML::Compile, with which I
have had good results.

As for how to architect this, consider not "how would I build this in
Catalyst" but "how would I build this standalone". Both from a
perspective of layered design, and of testing, this will simplify your

Once you have a standalone package wrapping your SOAP API and any
client-side business logic, wrap this up into a Catalyst model. You
may get good mileage with C::Model::Adaptor (or one of the other
patterns in its dist, e.g. ::Factory::PerRequest, if you need
per-request SOAP connection semantics) or by writing your own model
package that uses ACCEPT_CONTEXT to extract config etc from the
Catalyst context object. Also look at the
C::Component::InstancePerContext role, if you need per-request model
instantiation / configuration.
