+//! Parse `Fragments` into the Fragment VNode
+//! ==========================================
+//!
+//! This parsing path emerges from [`AmbiguousElement`] which supports validation of the Fragment format.
+//! We can be reasonably sure that whatever enters this parsing path is in the right format.
+//! This feature must support:
+//! - [x] Optional commas
+//! - [ ] Children
+//! - [ ] Keys
