# ElementNode

Represents an HTML, SVG, MathML, or foreign-content element with children.

## Signatures

```ts
export declare class ElementNode {
    readonly _tag = "element";
    readonly tagName: string;
    readonly attributes: Array<Attribute>;
    readonly children: Array<Node>;
    constructor(tagName: string, attributes: Array<Attribute>, children: Array<Node>);
}
```

## Why

Keeping the authored tag, attributes, and children explicit lets DOM
compilation apply native namespace rules and SSR preserve author markup.

## Ownership and lifetime

The model owns only parsed arrays and strings, never the eventual Element.

## Constructor

Creates an element AST node.

## Constructor: Why

Renderer tooling can construct native element syntax explicitly.

## Constructor: Ownership and lifetime

Retains supplied data and creates no Element.

## Property: _tag

Element-node discriminant.

## Property: _tag: Why

Enables exhaustive compilation.

## Property: _tag: Ownership and lifetime

Immutable AST metadata.

## Property: attributes

Parsed attributes in author order.

## Property: attributes: Why

Keeps distinct native directive semantics.

## Property: attributes: Ownership and lifetime

Retained AST array; no Attr ownership.

## Property: children

Parsed child structure.

## Property: children: Why

Defines the element's compile-time subtree.

## Property: children: Ownership and lifetime

Retained AST array; no DOM ownership.

## Property: tagName

Authored qualified tag name.

## Property: tagName: Why

Preserves native namespace-sensitive creation.

## Property: tagName: Ownership and lifetime

Retained string metadata.

## Examples

```ts
import { ElementNode } from "@typed/template/Template"

const node = new ElementNode("section", [], [])
```
