Reparse element with same reader

[Zekfad]

I'm in process of writing annotation (php 8.3) based (de)serialize methods and thinking about how to implement polymorphic node (select in xsd).

While it's possible to make an educated guess, meaning analyze candidate structures and try to see which one xml is actually follows, I think that solution is overly complicated to get it right.

I think of a try-catch parsing every candidate until first match. But to do so I need a way to reparse element with current reader options.

I'm thinking about cloning reader options to a new one and use fragment to get a stable copy of element descendants. Is there any better or convenient ways to achieve it?
