This is indeed one of the easiest things, but it would be TOTALLY
wrong.
http://www.w3.org/TR/xmlschema-2/datatypes.html#anyURI says, among else:
The mapping from anyURI values to URIs is as defined by the URI reference
escaping procedure defined in Section 5.4 Locator Attribute of [XML
Linking Language] (see also Section 8 Character Encoding in URI References
of [Character Model]). This means that a wide range of internationalized
resource identifiers can be specified when an anyURI is called for, and
still be understood as URIs per [RFC 2396], as amended by [RFC 2732],
where appropriate to identify resources.
If there is confusion in other venues about this issue, please help
to make sure it gets fixed.
