Actually, it does make sense to have the idea of different contexts for validating domain objects. At Notiva, some people took the validation stuff from Xwork and built a pattern for validating our business objects using the Visitor Pattern to bring the validation down to the sub-object level. We have different validations depending on where we're getting the objects (batch loading from XML from a partner vs. data-entry, etc.) so we used the idea of context (the same as alias) for this. I'm planning on merging this code back into Xwork at some point. I'm still thinking about if we can make it simpler using reflection rather than the visitor object we use now that knows the structure of the business objects, but the basic idea is sound.
