### Category User level API changes ### Describe the feature you'd like to request Hi team! Rust supports schema fragments, which allow to define multiple schemas and concatenate them using [Schema::from_schema_fragments()](https://docs.rs/cedar-policy/latest/cedar_policy/struct.Schema.html#method.from_schema_fragments). Could this be added to cedar-java please? Our company would like to have multiple schemas to support division of teams/domains since we have a broad set of thousands of actions. Then we would like to pass them as a single schema to the engine. Another option is to allow the engine to accept multiple schemas. This is highly helpful for enterprise applications, because management of a single schema becomes difficult. ### Describe alternatives you've considered Create our custom concatenation logic, but this could be error-prone and Rust already supports it! ### Additional context _No response_ ### Is this something that you'd be interested in working on? - [ ] 👋 I may be able to implement this feature request - [ ] ⚠️ This feature might incur a breaking change
