* Check if a virtual node matches some definition

* Example:
* ```js
* matches.fromDefinition(vNode, {
* nodeName: ['div', 'span']
* attributes: {
* 'aria-live': 'assertive'
* }
* })
* ```
*
* @deprecated HTMLElement is deprecated, use VirtualNode instead

* @private
* @param {HTMLElement|VirtualNode} vNode
* @param {Object|Array<Object>} definition
* @returns {Boolean}
