 * `output` (string, optional): if the node specified by `nodename` has multiple outputs, the name of the specific output to connect this <output> to.
 * `uniform` (boolean, optional): If set to "true", then the output of this node is treated as a uniform value, and this output may be connected to a uniform input of the same (or compatible) type.  It is up to the application creating the nodegraph to ensure that the value actually is uniform.  Default is "false".

These attributes do **not** affect values from this <output> connected to other nodes, e.g. they would remain in the working colorspace and retain full resolution and bitdepth precision.

 * `colorspace` (string, optional): the name of the color space for the output image.  Applications that support color space management are expected to perform the required transformations of output colors into this space.
 * `width` (integer, optional): the expected width in pixels of the output image.

 * **`switch`**: output the value of one of up to ten input streams, according to the value of a selector input `which`.  Switch nodes can be of output type float, color<em>N</em> or vector<em>N</em>, and have five inputs, in1 through in10 (not all of which must be connected), which must match the output type.

The types of the various `in<em>N</em>` inputs must match the type of the `switch` node itself.  The default value of all `in<em>N</em>` inputs is 0.0 in all channels.

So `which`&lt;1 will pass on the value from in1, 1&lt;=`which`&lt;2 will pass the value from in2, 2&lt;=`which`&lt;3 will pass the value from in3, and so on up to 9&lt;=`which` will pass the value from in10.  The default value of `which` is 0.
