Module errors 

Validation error types for instance validation

This module provides spec-aligned error codes for XML instance validation against XSD schemas. Error codes follow the XSD specification anchors:

• cvc-* - Instance validation constraints (e.g., cvc-elt, cvc-type)
• cos-* - Component constraints (e.g., cos-valid-default)
• src-* - Schema representation constraints (e.g., src-element)

Structs
