+				dialplan context to use for the newly created dynamic parking lot. If
+				not set then the context from the parking lot template is used. The
+				context is created if it does not already exist and the new parking lot
+				needs to create extensions.

+				<literal>parkext</literal> to use for the newly created dynamic
+				parking lot. If not set then the <literal>parkext</literal> is used from
+				the parking lot template. If the template does not specify a
+				<literal>parkext</literal> then no extensions are created for the newly
+				created parking lot. The dynamic parking lot cannot be created if it
+				needs to create extensions that overlap existing parking lot extensions.
+				The only exception to this is for the <literal>parkext</literal>
+				extension and only if neither of the overlaping parking lot's
+				<literal>parkext</literal> is exclusive.

+			<para>The <variable>PARKINGDYNPOS</variable> variable specifies the
+				parking positions to use for the newly created dynamic parking lot. If

+				<para>This application must be used as the first extension priority

+					Blind transfers and the DTMF one-touch parking feature need this

+					this case is treated like a dialplan hint.
