+This extension defines a feature, rsz:resize, which allows plugins to
+dynamically resize their output port buffers.

+In addition to the dynamic feature, there are properties which describe the

+rsz:resize
+	lv2:documentation """
+
+A feature to resize output port buffers in LV2_Plugin_Descriptor::run().
+
+To support this feature, the host must pass an LV2_Feature to the plugin's
+instantiate method with URI LV2_RESIZE_PORT__resize and a pointer to a
+LV2_Resize_Port_Resize structure.  This structure provides a resize_port
+function which plugins may use to resize output port buffers as necessary.
+
+"""^^lv2:Markdown .
+
+rsz:asLargeAs
+	lv2:documentation """
+
+Indicates that a port requires at least as much buffer space as the port with
+the given symbol on the same plugin instance.  This may be used for any ports,
+but is generally most useful to indicate an output port must be at least as
+large as some input port (because it will copy from it).  If a port is
+asLargeAs several ports, it is asLargeAs the largest such port (not the sum of
+those ports' sizes).
+
+The host guarantees that whenever an ObjectPort's run method is called, any
+output `O` that is rsz:asLargeAs an input `I` is connected to a buffer large
+enough to copy `I`, or `NULL` if the port is lv2:connectionOptional.
+
+"""^^lv2:Markdown .
+
+rsz:minimumSize
+	lv2:documentation """
+
+Indicates that a port requires a buffer at least this large, in bytes.  Any
+host that supports the resize-port feature MUST connect any port with a
+minimumSize specified to a buffer at least as large as the value given for this
+property.  Any host, especially those that do NOT support dynamic port
+resizing, SHOULD do so or reduced functionality may result.
