should not be used to generate json/xml reponse....

Is this still true?

If it's true why not simply create an h:html tag which should be like f:view
and remove the f:metadata tag ?

In this way it would be possible to create a template or a page in a simpler and more linear way, for example:
```

```

```

Hello templating

Hello templating

```

Start by reviewing the linked Stack Overflow discussion and the existing JSF behavior around f:view and f:metadata. The issue proposes a new h:html element and a different metadata structure, but names no source files or tests; done would require an agreed design, implementation scope, and validation criteria.
