Struct DutmalMetadata 

#[non_exhaustive]
pub struct DutmalMetadata {
    pub option: u32,
}

Wire-mirrored metadata attached to a Control::Dutmal.

Carries HWPX <hp:dutmal> attributes that HwpForge does not yet model as typed fields — currently just option. Field is mirrored verbatim from HWP5 wire / HWPX option= attribute and emitted verbatim on encode so round-trips preserve the value even when the semantics aren’t pinned down (see .docs/algorithms/2026-06-01_dutmal_carry.md).

#[non_exhaustive] — additions like style_id_ref or the two reserved tail words are additive and don’t break existing destructure / pattern-match sites.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

option: u32

<hp:dutmal option=…> value mirrored verbatim. Likely a bit-field or enum on the HWPX side; HwpForge treats it as an opaque u32 until the spec is confirmed.
