modelId

Stable identifier for this model within its enclosing bundle. Used as a directory name inside the JAR (under META-INF/ksl/models/) and as the cache filename for the lazy descriptor extractor; must therefore be filesystem-safe (lowercase ASCII letters, digits, and hyphens by convention; no slashes, no ..).

Two different bundles may legally reuse the same modelId. The global key is the pair (KSLModelBundle.bundleId, KSLBundledModel.modelId).
