+    4.5.  URI RDATA Wire Format
+
+        The RDATA for a URI RR consists of a 2-octet Priority field, a
+        2-octet Weight field, and a variable-length Target field.
+
+        Priority and Weight are unsigned integers in network byte order.
+
+        The remaining data in the RDATA contains the Target field.  The
+        Target field contains the URI as a sequence of octets (without the
+        enclosing double-quote characters used in the presentation format).
+
+        The length of the Target field MUST be greater than zero.
