Struct AttributeDescriptor 

pub struct AttributeDescriptor {
    pub key: String,
    pub label: String,
    pub kind: OptionKind,
    pub quantity: Option<String>,
}

Description of one attribute an application may display for elements of a kind (spec §4.4).

Reuses the option-descriptor value vocabulary (OptionKind, spec §3.2.1) and is advisory in exactly that sense: it tells a generic UI what to show; it is not the validation authority, and an engine remains free to hold data no schema advertises. This revision describes attributes for display; editability, defaults, and creation flows are a later additive revision.

Fields

key: String

Field name in the element’s attribute data. Stable per kind; renaming one is a break, like a block id.

label: String

Human-facing name.

kind: OptionKind

Value shape and bounds.

quantity: Option<String>

Key of the physical quantity the value carries (spec §5), or None for dimensionless or textual attributes.
