+        <entry>Validates value as URL (according to <link xlink:href="&url.rfc;2396">&url.rfc;2396</link>), optionally with required components. Beware a valid URL may not specify the HTTP protocol <parameter>http://</parameter> so further validation may be required to determine the URL uses an expected protocol, e.g. <parameter>ssh://</parameter> or <parameter>mailto:</parameter>. Note that the function will only find ASCII URLs to be valid; internationalized domain names (containing non-ASCII characters) will fail.</entry>
