+TLD Services Overview</title><shortdesc>This document introduces the Whitelist/Blacklist Top-Level Domain
+services of the InetURIList framework. </shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>International domain names support increases the vulnerability of the device
+to homograph attacks (also called phishing), by allowing addresses (URIs)
+to contain UTF-8 characters. By using non-ASCII characters that are visually
+similar to familiar letters, attacks can lead the Internet user to harmful
+sites. </p>
+<p>To address this issue, the InetURIList framework provides a list of suspect
+characters (a BlackList) for each top-level domain (TLD). The framework also
+lists trusted characters in TLD-specific WhiteLists. This enables applications
+to detect safe and unsafe URIs depending on their top-level domain and the
+characters they contain. </p>
+<p>The Blacklists and Whitelists are stored in an XML file installed on the
+device. You can replace the default TLD policy file by installing an SIS package
+containing the updated lists. </p>
+<p>Applications can query the TLD list but cannot dynamically change its contents. </p>
