Rail Specification Language For Declarative Validation Schemas

LLM output validation framework with auto-correction.

Unique: Introduces RAIL, a domain-specific XML language that enables declarative definition of validation schemas, validators, and failure handling strategies without Python code. RAIL specifications are human-readable, version-controllable, and can be edited by non-developers.

vs others: More accessible than Pydantic models for non-technical users because RAIL is declarative and human-readable; more portable than Python code because RAIL specifications are language-agnostic and can be shared across teams.
