/**
 * Used by mapping model classes to fail fast when an element has mapping errors. The caller must
 * report errors itself (with {@link ProcessingContext#addError}) before throwing. Note that {@link
 * MappingModel#build} will fail at the end if any errors have been reported, so it's fine to
 * swallow this exception and keep going if the code wants to report as many errors as possible.
 *
 * This exception is used for flow control only, it never surfaces to the client directly.
