+    Attribute interface describing a target device description specification.
+
+    A target device description specification is a list of device properties (key)
+    and their values for a specific device. The device is identified using "device_id"
+    (as a key and ui32 value) and "device_type" key which must have a string value.
+    Both "device_id" and "device_type" are mandatory keys. As an example, L1 cache
+    size could be a device property, and its value would be a device specific size.
+
+    A target device description specification is attached to a module as a module level
+    attribute.

Ok, I think we need to have a better API for this anyway, but this PR is already too long to get there. We can have as fewer restrictions as we can right now to not make that harder in the near future.
