Have you not got one of these handed to you from something?
Or are you right at the outside with some "opaque" blender handle or

Thank you once again.
If I understand your question, I am right outside. By this I mean I
have not created anything with Python. I have made the Blender model
with the UI and am trying to use Python to read the values for the
settings used. This has worked for all settings except this Map Value
Node.
Hmm. So you have a CompositorNodeMapValue instance? If that is the case
you should be able to inspect it as previously described.
However, it looks like this is something you construct in order to do
some task. A little web searching turns up this stackexchange post:
https://blender.stackexchange.com/questions/42579/render-depth-map-to-image-with-python-script/42667
and some example code from an unrelated project:
https://github.com/panmari/stanford-shapenet-renderer/blob/master/render_blender.py
From the stackexchange post:
map = tree.nodes.new(type="CompositorNodeMapValue")
# Size is chosen kind of arbitrarily, try out until you're satisfied
# with resulting depth map.
map.size = [0.08]
map.use_min = True
map.min = [0]
map.use_max = True
map.max = [255]
"tree" is "bpy.context.scene.node_tree".
Aside from "map" being a poor name (it is also a builtin Python
function), it seems that one creates one of these to control how some
rendering process is done.
The class reference page you originally cites then specifies the meaning
of the various attributes you might set on one of these objects.
