 | <a name="xml-name"></a>name | `string` | Replaces the name of the element/attribute used for the described schema property. When defined within `items`, it will affect the name of the individual XML elements within the list. When defined alongside `type` being `"array"` (outside the `items`), it will affect the wrapping element if and only if `wrapped` is `true`. If `wrapped` is `false`, it will be ignored. |
-| <a name="xml-namespace"></a>namespace | `string` | The URI of the namespace definition. Value MUST be in the form of a non-relative URI. |
+| <a name="xml-namespace"></a>namespace | `string` | The IRI ([[RFC3987]]) of the namespace definition. Value MUST be in the form of a non-relative IRI. |
 | <a name="xml-prefix"></a>prefix | `string` | The prefix to be used for the [name](#xml-name). |
 | <a name="xml-attribute"></a>attribute | `boolean` | Declares whether the property definition translates to an attribute instead of an element. Default value is `false`. |
 | <a name="xml-wrapped"></a>wrapped | `boolean` | MAY be used only for an array definition. Signifies whether the array is wrapped (for example, `<books><book/><book/></books>`) or unwrapped (`<book/><book/>`). Default value is `false`. The definition takes effect only when defined alongside `type` being `"array"` (outside the `items`). |

 The `namespace` field is intended to match the syntax of [XML namespaces](https://www.w3.org/TR/xml-names11/), although there are a few caveats:
 
-* Versions 3.1.0, 3.0.3, and earlier of this specification erroneously used the term "absolute URI" instead of "non-relative URI", so authors using namespaces that include a fragment should check tooling support carefully.
-* XML allows but discourages relative URI-references, while this specification outright forbids them.
-* XML 1.1 allows IRIs ([RFC3987](https://datatracker.ietf.org/doc/html/rfc3987)) as namespaces, and specifies that namespaces are compared without any encoding or decoding, which means that IRIs encoded to meet this specification's URI syntax requirement cannot be compared to IRIs as-is.
