+<p>Defines ports which contain string data.</p>
+
+<h4>UI issues</h4>
+<p>When using port_event / write_port (and possible other communication
+mechanisms), the format parameter should contain the numeric value of URI
+LV2_STRING_PORT_URI (mapped with http://lv2plug.in/ns/extensions/ui specified
+as map URI).</p>
+
+<p>It's probably possible to use ports belonging to message context
+&lt;http://lv2plug.in/ns/ext/contexts#MessageContext&gt; for transfer. However,
+contexts mechanism does not offer any way to notify the message recipient about
+which ports have been changed. To remedy that, this extension defines a flag
+LV2_STRING_DATA_CHANGED_FLAG that carries that information inside a port value
+structure.</p>
+
+<h4>Storage</h4>
+<p>The value of string port are assumed to be "persistent": if a host saves and
+restores a state of a plugin (e.g. control port values), the values of input
+string ports should also be assumed to belong to that state. This also applies
+to message context: if a session is being restored, the host MUST resend the
+last value that was sent to the port before session has been saved. In other
+words, string port values "stick" to message ports.</p>

+
+<h4>Input Port Semantics</h4>
+<p>If the port does not have a context specified (it runs in the default,
+realtime audio processing context), the values in the structure and the actual
+string data MUST remain unchanged for the time a run() function of a plugin
+is executed. However, if the port belongs to a different context, the same
+data MUST remain unchanged only for the time a run() or message_process()
+function of a given context is executed.</p>
+
+<h4>Output Port Semantics</h4>
+<p>The plugin may only change the string or length in a run() function (if
+the port belongs to default context) or in context-defined counterparts
+(if the port belongs to another context). Because of that, using default
+context output string ports is contraindicated for longer strings.</p>
