Validator (Closure Compiler)

java.lang.Object
- com.google.javascript.jscomp.jsonml.Validator

```
public class Validator
extends java.lang.Object
```
Statically validates JsonML elements. It is done in constant time: no subtree is traversed, but the element is validated based only on its properties. Sometimes, also its children are taken into account. Usually it checks if the specified element has a correct number of children, and if all require attributes exist. It does not enforce all restrictions which are implied by ES3 or ES5 specification.
