 - `<attr-name>`
   - : The attribute name whose value should be retrieved from the selected HTML element(s).
+    - Namespaces
+      - : The attribute name can contain a [`namespace`](/en-US/docs/Web/CSS/Guides/Namespaces) which allows the targeting elements of [XML](/en-US/docs/Web/XML)-based markup languages such as [SVG](/en-US/docs/Web/SVG) or [MathML](/en-US/docs/Web/MathML).

+
+        > [!NOTE]
+        > If no namespace is specified (just an identifier is given, like `attr(foo)`), the null namespace is implied. This is usually what's desired, as namespaced attributes are rare. As with attribute selectors, the case-sensitivity of `<attr-name>` depends on the document language.

 - `<attr-type>`
   - : Specifies how the attribute value is parsed into a CSS value. This can be the `raw-string` keyword, a {{cssxref("type()")}} function, or a CSS dimension unit (specified using an `<attr-unit>` identifier). When omitted, it defaults to `raw-string`.
