pub const MAX_TREE_DEPTH: usize = 64;Expand description
DoS cap for the recursive tree depth.
Protects the recursive build_element call from stack overflow
on adversarial deeply-nested XML inputs (TS-1 finding 3,
internal/test-harness/plan.md). Realistic DDS-XML profiles go
4-8 deep; even complex <application>/<participant>
nestings stay below 32.
