+## Integration

+**remark-validate-links** can detect anchors on nodes through
+several properties on nodes:
+
+*   `node.data.htmlAttributes.name` — Used by [`remark-html`][remark-html]
+    to create a `name` attribute, which anchors can link to;
+
+*   `node.data.htmlAttributes.id` — Used by [`remark-html`][remark-html]

+*   `node.data.id` — Used, in the future, by other tools to signal
+    unique identifiers on nodes.
