It encodes inheritance, properties, and events.\n *\n * ## Overview\n *\n * Each line represents one kind of element. The `element_inheritance` and properties are joined\n * using `element_inheritance|properties` syntax.\n *\n * ## Element Inheritance\n *\n * The `element_inheritance` can be further subdivided as `element1,element2,...^parentElement`.\n * Here the individual elements are separated by `,` (commas). Every element in the list\n * has identical properties.\n *\n * An `element` may inherit additional properties from `parentElement` If no `^parentElement` is\n * specified then `\"\"` (blank) element is assumed.\n *\n * NOTE: The blank element inherits from root `[Element]` element, the super element of all\n * elements.\n *\n * NOTE an element prefix such as `:svg:` has no special meaning to the schema.\n *\n * ## Properties\n *\n * Each element has a set of properties separated by `,` (commas). Each property can be prefixed\n * by a special character designating its type:\n *\n * - (no prefix): property is a string.\n * - `*`: property represents an event.\n * - `!`: property is a boolean.\n * - `#`: property is a number.\n * - `%`: property is an object.\n *\n * ## Query\n *\n * The class creates an internal squas representation which allows to easily answer the query of\n * if a given property exist on a given element.\n *\n * NOTE: We don't yet support querying for types or events.\n * NOTE: This schema is auto extracted from `schema_extractor.ts` located in the test folder,\n * see dom_element_schema_registry_spec.ts\n */\nvar SCHEMA = [\n
