/**
 * Returns a node containing JSON Schema of a data JSON Pointer.
 *
 * To resolve dynamic schema where the type of JSON Schema is evaluated by
 * its value, a data object has to be passed in options.
 *
 * Per default this function will return `undefined` schema for valid properties
 * that do not have a defined schema. Use the option `withSchemaWarning: true` to
 * receive an error with `code: schema-warning` containing the location of its
 * last evaluated json-schema.
 *
 * @returns { node } or { error } where node can also be undefined (valid but undefined)
