If you prefix any of your element's attributes with a
w: it becomes a flag.
Flags are passed to
this.flags and are recommended for namespacing your "service" attributes.
WebComp also pre-defines some flags that change the behavior of WebComp components:
If this flag is set, content of a custom tag won't be passed to
this.props.children when component is rendered.
This flag locks external attribute manipulation. If an external force like jQuery is trying to change an element with this flag, changes won't be passed down to
this.props and it will throw an error.
