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