Every term in this category is listed as one record, with its kind, its definition and its aliases, the principles whose relations name it, the principle or contract that carries the same name where one exists, and the layer its category belongs to. A tag category also gives each term an example, which is the file the tag places or the rename from a refused word onto a covering tag. ### Capability Addition without Core Modification - Kind: [capability](https://banes-lab.com/records/kind/capability.md) - Category: [Runtime Discovery / Dynamic Binding](https://banes-lab.com/ontology/lexicon/lexicon-category-runtime-discovery-dynamic-binding.md) - Layer: [Extensibility Core](https://banes-lab.com/records/layer/extensibility-core.md) Details Definition The ability to add new capabilities at runtime without modifying the core.
